2916 PWM CURRENT CONTROL The UDx2916 dual bridges drive both windings of a bipolar stepper motor. Output current is sensed and controlled independently in each bridge by an external sense resistor, RS , internal comparator, and monostable multivibrator. When the bridge is turned on, current increases in the motor winding and it is sensed by the external sense resistor until the sense voltage, VSENSE , reaches the level set at the comparator input: ITRIP = VREF /10 RS The comparator then triggers the monostable, which turns off the source driver of the bridge. The actual load current peak will be slightly higher than the trip point (especially for low-inductance loads) because of the internal logic and switching delays. This delay, td , is typically 2 s. After turn-off, the motor current decays, circulating through the ground-clamp diode and sink transistor. The source driver off-time (and therefore the magnitude of the current decrease) is determined by the external RC timing components of the monostable: toff = RTCT where: RT = 20 to 100 k, and CT = 100 to 1000 pF. The xed off-time should be short enough to keep the current chopping above the audible range (< 46 s) and long enough to properly regulate the current. Because only slow-decay current control is available, short off times (< 10 s) require additional efforts to ensure proper current regulation. Factors that can negatively affect the ability to properly regulate the current when using short off times include: higher motorsupply voltage, light load, and longer than necessary blank time. When the source driver is re-enabled, the winding current (the sense voltage) is again allowed to rise to the comparator’s threshold. This cycle repeats itself, maintaining the average motor winding current at the desired level. Loads with high distributed capacitances may result in high turn-on current peaks. This peak (appearing across RS) will attempt to trip the comparator, resulting in erroneous current control or high-frequency oscillations. An external RCCC time delay should be used to further delay the action of the comparator. Depending on load type, many applications will not require these external components (SENSE connected to E).
