ISL6115A 12V Power Distribution Controllers ISL6115A Features HOT SWAP Single Power Distribution Control for This fully featured hot swap power controller targets +12V +12V applications. The ISL6115A with its integrated charge pump has a higher (6.5V vs 5V) gate drive Overcurrent Fault Isolation than its sister part the ISL6115 making this part an Programmable Current Regulation Level immediate efficiency improvement replacement. Programmable Current Regulation Time to This IC features programmable overcurrent (OC) Latch-Off detection, current regulation (CR) with time delay to Rail-to-Rail Common Mode Input Voltage Range latch-off and soft-start. Enhanced Internal Charge Pump Drives N-Channel The current regulation level is set by 2 external MOSFET gate to 6.5V above IC bias. resistors R sets the CR Vth and the other is a ISET Undervoltage and Overcurrent Latch Indicators low ohmic sense resistor across, which the CR Vth is Adjustable Turn-On Ramp developed. The CR duration is set by an external Protection During Turn-On capacitor on the CTIM pin, which is charged with a 20A current once the CR Vth level is reached. The Two Levels of Overcurrent Detection Provide Fast IC then quickly pulls down the GATE output latching Response to Varying Fault Conditions off the pass FET. 1s Response Time to Dead Short Pb-Free (RoHS Compliant) Applications Power Distribution Control Hot Plug Components and Circuitry Application Circuits - High Side Controller LOAD + - 1 8 PWRON ISL6115A 2 7 PGOOD 3 6 OC 4 5 +12V +V SUPPLY TO BE CONTROLLED April 23, 2010 CAUTION: These devices are sensitive to electrostatic discharge follow proper IC Handling Procedures. 1 1-888-INTERSIL or 1-888-468-3774 Intersil (and design) is a registered trademark of Intersil Americas Inc.
