ISL6115A
12V Power Distribution Controllers
DATASHEET
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; RISET sets the CR Vth and the other is a
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.
