Power Management ICs (Switch ICs) 


New Package : 

Switch ICs 

As for both portable and non-portable devices, electrical equipment are requested to minimise current consumption to save energy. 

Therefore electrical equipment activate only specific circuits depending on the operating mode of the application. A common solution was to 

use a discrete FET as a switch to shutdown the specific circuit blocks, however additional features for protection are needed. 

Ricoh provides various solutions of switch ICs featuring a low ON resistance MOSFET and the required protection circuits into a single chip.

• USB High-side Switch 

The functions of the USB high-side switch are mainly as follows: 

•ON/OFF control of the USB power line 

By an enable signal from the USB host controller, the USB highside 

switch turns on USB power line smoothly with its soft-start 

function and turns off to cut off the external low-side device. 

• Protection of the USB power line 

In addition to an abnormal over heat protection, when the USB 

high-side switch detects an over current , it limits an over current 

to a constant current or cuts off a USB power line by latch-off 

protection function.

• Rectifier Switch Products Lineup 

In general, a diode is used as a protection when a battery is inserted in a reversed direction. However, the device is blocked to operate in this case and in normal case a power loss 

occurs due to the forward voltage drop. When using the R5590x, a forward voltage drop does not occur and the device operates normaly regardless of the battery direction.

• Load Switch 

In some applications, it is necessary that a single power line 

supplies power to multiple peripheral circuits, a common solution 

is to use LDOs to distribute power lines. However, LDOs operation 

causes a dropout voltage and a significant power loss in terms 

of heat. Additionally LDOs need external capacitors for a stable 

operation. 

A load switch cannot regulate the output voltage, but the dropout 

voltage is very small because of the low on resistance of the 

internal transistor. The load switch suppresses power loss, and 

external capacitors are not necessary. In addition, the Ricoh's load 

switch can operate in very low voltage conditions.

• Intelligent Power Switch 

Intelligent power switch protects power lines. R5550K can detect two different over current thresholds and an under voltage error. When 

the R5550K detects over current, the switch turns off after the preset delay time. If an abnormal voltage is detected, the switch turns off 

after the preset delay time (10ms). After detecting the abnormal situation, the switch turns on again automatically if the cause of the error 

is removed.

• Battery Power Line Switch 

A battery power line switch IC can prevent an inrush current at start up by a soft start 

circuit. The R5527K has a build-in reverse current protection circuit at ON and OFF state, an 

easy and compact solution compared to a discrete FET. This switch is able to use as a load 

switch.

• Power Selector Switch 

Nowadays hand-held equipments such as smartphones and 

tablet PCs are able to charge not only from AC adapter and USB 

power but also from a new wireless charger method. 

In such case, it is necessary that the PMIC selects between two 

charger circuits. This selector circuit can be made easily by using 

two R5528Z ICs. 

The maximum output current of R5528Z is 3A, so it can be used 

in equipment using a large battery.

• Initially the DC/DC starts-up and charges a large output capacitor. 

When fully charged above the threshold of the VD, the DC/DC will be 

disabled. The LDO consumes charge from the capacitor and provides 

a stable output. As soon the charge drops below the threshold of the 

VD, the DC/DC is enabled again. This sequence is repeating. 

• RP600K2xxC operates as ultra low power consumption step-up and 

step-down power supply. 


• DC/DC output voltage is adjustable by external resistors. 

• LDO output (OUT2) operates as step-up and step-down power supply.

Ps: P-channel source pin for over-charge alarm output * 

*) Alarm output pin (AOUT) is a P-channel open drain output. 

In the R5464K, the source of AOUT is Ps pin, not VDD pin. Therefore, the 

external pull-down resistor, R6 does not have an impact on the drop out 

between a plus terminal of a battery pack and a VDD pin. Thus, R6 value 

range is wide enough to choose. 

– 

When cell 1 voltage or cell 2 voltage exceeds the alarm threshold voltage 

(VALML), an alarm signal will be present at the AOUT pin. If the detection 

temperature of thermistor exceeds 45°C, the alarm detect voltage threshold 

changes to VALMH. 

(The detection temperature can be changed)

• Breaking Wire Detection 

In case of using a battery pack in electric power tools 

exposed to heavy vibrations, there is a risk that the protection 

circuit fails due to a breaking wire condition between battery 

cells and protection circuit board. 

The Breaking Wire Detection circuit performs a test at 

fixed intervals, depending on the capacitance connected to 

CTLT pin. When a breaking wire event occurs, it results in 

interrupting the charge or discharge condition. 

• Cascade Connection 

Multi cell Li-ion/polymer battery protection ICs can protect 

over 6cells by cascade connection. 

17 

When a cell voltage is lower than the cell balance threshold, a cell is charged. 

When a cell voltage becomes higher than the cell balance threshold, CB1 pin becomes "H" and 

N-channel transistor turns on, and then the cell balance operation starts. Then a bypass current 

flows to the direction of a arrow and a charge current becomes suppressed by the bypass current. 

When a cell voltage reaches to the over-charge threshold, cell charging stops after the output delay time. 

If charging to a cell stops, the cell balance operation continues until a cell voltage 

becomes lower than the cell balance released threshold. The bypass current continues to 

flow decreasing the cell voltage. 

When a cell voltage reaches to the cell balance released voltage, CB1 pin becomes "L" 

and N-channel transistor turns off, and then cell balance operation stops.

It means the consumption current which operates only clock and calendar without accessing CPU. 

It means the voltage which operates only clock and calendar without accessing CPU. 

The operating voltage to access CPU is specified in the other specification. 

It means the function which outputs the interrupt signal at the setting time. 

It means the interrupt function which outputs at constant periodic such as every seconds, every minutes, every hours and 1 month. 

It is useful when indicating clock and calendar by using the RTC clock data. 

It is possible to output same clocks of crystal frequency which is used in RTC. There are four types of selectable outputs such as Open drain 

controllable by pin, Open drain keeping output enable, CMOS controllable by pin, CMOS with level shifter. It is suitable for CPU sub-clock. 

It means the circuit which adjusts time gain or loss by the software. It is useful to compensate the crystal frequency deviation. 

The circuit records past oscillation halt to internal register. 

It can be used to judge the validity of internal data in such events as power-on. 

It records them as Flag when detecting voltage threshold of backup battery. 

It is useful as checker of the output voltage for backup battery. 

RTC generally use 32768Hz crystal oscillator. But RS5C372A/B can select 32000Hz crystal oscillator as well as 32768Hz 

crystal oscillator. 32KOUT pin outputs 32000Hz clock pulses when 32000Hz crystal oscillator is used. 

R2051x, R2061x, R2062L, R2251L * , R2262L, R2286L * and R2296L * incorporate the automatic switch-over circuit which can switch between a main 

power supply and a back-up battery. Primary battery, secondary battery, electric double layered capacitor or aluminum electrolytic capacitor are 

selectable as backup battery in R2051x, R2061x, R2251L, R2286L* and R2296L*. Secondary battery, electric double layered capacitor or aluminum 

electrolytic capacitor are selectable as backup battery in R2062L and R2262L. R2262L includes VR for charger. 

R2025S/D and R2045S/D incorporates 32768Hz crystal unit. The oscillation frequency is adjusted to high precision.(0±5ppm:at 25°C) 

The deviation corresponds to ±15 seconds per every month. 

By using the clock adjustment circuit, time deviation also can be calibrated to 3 or 6 or 9±5ppm 

In the case that equivalent series resistance of crystal oscillator is low,(approximately equal or less than 45kΩ) time keeping 

current can be reduced, if ECO mode is active. There are a register setting type such as R2223x and R2243x * , and a pin setting 

type such as R2221x and R2251L * in the setting ECO mode. 

It is important that the tamper of meters for infrastructure such as power meters can be detected. Also it is necessary that the 

breaking a seal of an outer case can be detected in other applications. 

The event (tamper) detection is able to monitor the tamper action, because the RTC always operates even if the CPU stops in this system. 

When the event (tamper) is detected, the RTC sends an interrupt signal to the CPU and records the time to occurrence as a time stamp.

Real Time Clock ICs (Application Note) 

The merits to select Real Time Clock ICs 

Lower than the software control types in consumption current. 

Clock function can be also operated by software control. 

But Real Time Clock ICs is lower than the software control 

in consumption current. 

As smaller back-up devices are available, so high density 

mounting ICs on board is possible. 

Easier to develop the software 

It is very hard to develop clock and calendar software. 

The end date of months including leap year have to be 

calculated in calendar. 

And furthermore it has to be calculated by sexagesimal 

and the base 24 system. 

The Real Time Clock ICs incorporates the circuit can 

support to develop such a software. 

Easier to design a oscillation circuit 

The Real Time Clock ICs involve an oscillation 

circuit without a crystal. 

By simply using a crystal, layout of oscillation circuit 

can be configured. 

Anti-noise measurement can be made easily.

RICOH Real Time Clock ICs superior facilities 1 

RICOH Real Time Clock ICs have following functions. 

High-precision Oscillation 

The oscillation adjustment circuit is configured to 

change time counts of 1second on the basis of the 

setting of the oscillation. 

The adjustment is registered once in 20 seconds or 

60 seconds. 

The maximum range is approximately ±189ppm (or ±63ppm).

Do it per 20 seconds or 60 seconds 

*) R2025x and R2045x don't involve the adjustment function in 60 seconds. 

A tuning fork type crystal oscillator can output stable frequency. 

But the frequency is changed easily by the capacitances on a board. 

Generally, the capacitances have to be evaluated on PCB which is used in Mass-production. 

RICOH Real Time Clock ICs have settable registers to adjust time gain or loss. 

Furthermore it is useful to compensate the crystal frequency deviation.

The power-on reset flag and the oscillation halt sensing circuit are configured to confirm the established invalidation 

of time data in constant to the supply voltage monitoring circuit intended to confirm the potential invalidation of time data. 

The supply voltage monitoring circuit can be applied to battery supply voltage monitoring. 

• Power on reset 

Power on reset function reset the control registers when the system is powered on from 0V. 

At the same time, the fact is memorized to the registers as a flag, thereby identifying whether they are 

powered on from 0V or battery back-up. 

• Oscillation halt sensing function 

An oscillation halt sensing function records any past oscillation with internal registers. 

Thereby identifying whether any past oscillation halted. 

• Supply voltage monitoring function 

Supply voltage monitoring function records any drop in supply voltage of a certain threshold value with internal registers.

The back-up switch-over function is 

needed when the main power supply fell. 

But the configuration for back-up 

switch-over function is needed the 

measurements, due to the external 

diodes causing a voltage descent and 

the increasing of the consumption 

current. 

These products incorporate battery 

back-up switch-over circuits, any outside 

parts are not required. 

It can switch automatically between a

The R1116x Series are CMOS-based voltage regulator ICs with high output voltage accuracy, low supply 

current, low on Resistance, and high ripple rejection. Each of these ICs consists of a voltage reference unit, an 

error amplifier, resistor-net for voltage setting, a short current limit circuit, a chip enable circuit, and so on. 

These ICs perform with low dropout voltage and the chip-enable function. The supply current at no load of this 

IC is only 10μA, and the line transient response and the load transient response of the R1116x Series are 

excellent, thus these ICs are very suitable for the power supply for hand-held communication equipment. 

The supply current at no load of R1116x Series is remarkably reduced compared with R1114x Series. The 

mode change signal to reduce the supply current is not necessary. The output voltage accuracy is also improved. 

(±1.5%) 

The output voltage of these ICs is fixed with high accuracy. Since the packages for these ICs are SOT-23-5 

and SON1612-6 therefore high density mounting of the ICs on boards is possible. 

R1126N Series that a pin configuration differs from R1116N Series are available.

The R1116x Series are CMOS-based seamless LDO regulators featuring 150mA output. Ricoh unique seamless technology smoothly 

changes transient response according to a output current without switching to a low power mode. Thus, R1116x offers an ultra low 

supply current in the smaller output current range which is lower than the one of R1114x (Typ. 75μA). Additionally, this product can 

reach low supply current without changing mode only by using the ECO pin, which is required by R1162x Series (Typ. 5.5μA). The CE 

pin is capable of putting the product into standby mode. The version with an auto-discharge function is also available. The pin-out 

meets the standard requirements. Ceramic capacitors can be used.
