ISL6115AEVAL1Z開發(fā)板套件編程器的評估演示板及套件規(guī)格書PDF中文資料

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.
