DATASHEET ISL6115A FN6855 Rev 1.00 12V Power Distribution Controllers April 23, 2010 This fully featured hot swap power controller targets Features +12V applications. The ISL6115A with its integrated HOT SWAP Single Power Distribution Control for charge pump has a higher (6.5V vs 5V) gate drive +12V than its sister part the ISL6115 making this part an Overcurrent Fault Isolation immediate efficiency improvement replacement. Programmable Current Regulation Level This IC features programmable overcurrent (OC) Programmable Current Regulation Time to detection, current regulation (CR) with time delay to Latch-Off latch-off and soft-start. Rail-to-Rail Common Mode Input Voltage Range The current regulation level is set by 2 external Enhanced Internal Charge Pump Drives N-Channel resistors R sets the CR Vth and the other is a ISET MOSFET gate to 6.5V above IC bias. low ohmic sense resistor across, which the CR Vth is developed. The CR duration is set by an external Undervoltage and Overcurrent Latch Indicators capacitor on the CTIM pin, which is charged with a Adjustable Turn-On Ramp 20A current once the CR Vth level is reached. The Protection During Turn-On IC then quickly pulls down the GATE output latching Two Levels of Overcurrent Detection Provide Fast off the pass FET.
