capacitor to ground. Each cap is charged with a 1μA internal current source to an internal reference
voltage causing the corresponding gate to be pulled down thus turning-off the FET.
Drives the external FETs with a 10μA current source to soft start ramp into the load. During sequence
off, 10μA is sunk from this pin to control the FET turn-off. During a turn-off due to a fault, the gate will
sink ~75mA to ensure a rapid turn-off.
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.
