ISL6115A

12V Power Distribution Controllers

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 resistors;

element 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. If the voltage on the CTIM capacitor reaches

1.9V the IC then quickly pulls down the GATE output latching

off the pass FET.

Features

• HOT SWAP Single Power Distribution Control for +12V
