FUNCTION

As an input, allows for immediate and unconditional latch-off of all GATE outputs when driven low. This pin
can also be used to initiate the programmed sequence with ‘zero’ wait (no 10ms stabilization delay) from
input signal on this pin being driven high to first GATE.
As an output when there is a UV condition this pin pulls low. If common to other SYSRST# pins in a multiple
IC configuration it will cause immediate and unconditional latch-off of all other GATEs on all other ISL872x
sequencers.
This pin is released to go high once all UVLO and enable conditions are satisfied and is pulled low
concurrent with the last GATE being turned off after EN disabled.
