説明
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.
