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.
3VMAIN gate drive outputs connects to gate of an external N-Channel MOSFET. During power-up this pin charges
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.
100ms delayed report of MAIN supplies output voltage compliance.
each slot. tFILTER is the amount of time for which a slot remains in current limit before its circuit breaker is tripped.
