VCC1 supports an input range of 3V
to 5.5V in order to support both 3.3V and 5V controller signaling. VCC1 is monitored
with both an undervoltage and overvoltage comparator circuit to ensure valid operation.
UV and OV conditions of VCC1 are recorded in FAULT2[UVLO1_FAULT] and
FAULT2[OVLO_FAULT1], respectively.
