APPLICATION INFORMATION<br />
Timing Chart<br />
The timing chart can be helpful for engineers<br />
to see the operation of each pin of <strong>HM03145</strong><br />
and can be used to be the primary basis<br />
during the error detection. The timing chart of<br />
<strong>HM03145</strong> during the normal operation is as<br />
follows:<br />
Furthermore, when the protection of <strong>HM03145</strong><br />
occurs, its timing chart can be further categorized<br />
into three types. One is that when the output over<br />
voltage occurs, the PGOOD terminal will convert<br />
from the high level to the low level and output will<br />
be turned off if the output voltage is higher than<br />
the protection point. The timing for each pin is as<br />
follows:<br />
Figure 4. Normal Operation<br />
When it comes to start-up, it should be noted<br />
that the internal mechanism of <strong>HM03145</strong> does<br />
not allow the startup of PVCC to be faster than<br />
that of the input voltage, so in order to make it<br />
work normally, this problem should be avoided<br />
in applications.<br />
