12V Power Distribution Controllers

ISL6115A

This fully featured hot swap power controller targets

+12V applications. The ISL6115A with its integrated

charge pump has a higher (6.5V vs 5V) gate drive

than its sister part the ISL6115 making this part an

immediate efficiency improvement replacement.

This IC features programmable overcurrent (OC)

detection, current regulation (CR) with time delay to

latch-off and soft-start.

The current regulation level is set by 2 external

low ohmic sense resistor across, which the CR Vth is

developed. The CR duration is set by an external

capacitor on the CTIM pin, which is charged with a

20µA current once the CR Vth level is reached. The

IC then quickly pulls down the GATE output latching

off the pass FET.
