Shutdown

REG3 shuts down when either PWREN or PWRHLD go low. REG7/1/4/2/5 shut down by pressing nPBIN

for longer than 4s or by pulling PWRHLD low while GPIO1 is low.

nPBIN

nPBIN retains the short and long press functionality described earlier in the datasheet. A “short press” pulls

nRSTO low to reset the processor. A “long press” powers down all outputs. The outputs restart per the

defined sequencing when nPBIN is released after a “long press”

NRSTO

nRSTO is gated by REG5 and should be pulled up to REG5. nRSTO has a 40ms delay after REG5 goes

into regulation.
