12VGATEA,
12VGATEB
12VMAIN gate drive output, connects to gate of an external P-Channel MOSFET. During power-up, this pin is
pulled down with a 25µA (5µA for ISL6114) current to control the dv/dt ramp of the output voltage to the slot. During
CR, the voltage on this pin is modulated to maintain a constant current into the load. During power-down or
latch-off for an overcurrent fault, this pin is pulled high to 12VIN by internal sources.

3VGATEB
up with a 25µA (5µA for ISL6114) current to control the dv/dt ramp of the output voltage to the slot load. During
CRTIM the voltage on this pin is modulated to maintain a constant current into the load. During power-down or
latch-off for an overcurrent fault this pin is pulled low by internal sources.

PERSTA,
PERSTB
100ms delayed report of MAIN supplies output voltage compliance.

CFILTERA,
CFILTERB
A capacitor connected between each of these pins and ground sets the current regulated duration (tFILTER) for
each slot. tFILTER is the amount of time for which a slot remains in current limit before its circuit breaker is tripped.
