Over Current or Current Limit Faults
Over current or current limit faults are conditions when the load current that is being sensed trips either the I
CUT
comparator (570 mA to 665 mA) or the I
LIM
comparator (600 mA to 700 mA) and turns on the current fault timer.
When the over current timer reaches its time out limit that is set between 50 ms to 75 ms the corresponding port
is turned off and the over current fault code generated in the Port Status 1 register. If the over current condition
goes away prior to the over current timer reaching its limit the timer is reset and waits for the next event.
Figure 7
shows an over current fault lasting more than 50 ms that has caused the port to shut off.
