This IC targets dual voltage hot swap applications across the +2.5V to +3.3V (nominal) bias supply voltage range with a second lower voltage rail down to less than 1V where a circuit breaker response to an over current event is preferred. It features a charge pump for driving external N-Channel MOSFETs, accurate programmable circuit breaker current thresholds and delay output undervoltage monitoring and reporting and adjustable soft-start. Features • Fast Circuit Breaker Quickly Responds to Overcurrent Fault Conditions • Less than 1µs Response Time to Dead Short • Programmable Circuit Breaker Level and Delay • Two Levels of Overcurrent Detection Provide Fast Response to Varying Fault Conditions • Overcurrent Circuit Breaker and Fault Isolation Functions • Adjustable Circuit Breaker Threshold as Low as 20mV • Adjustable Voltage Ramp-up for In-Rush Protection During Turn-On • Rail Independent Control, Monitoring and Reporting I/O • Dual Supply Hot Swap Power Distribution Control to <1V • Charge Pump Allows the Use of N-Channel MOSFETs • QFN Package: - Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat No Leads - Package Outline - Near Chip Scale Package Footprint, Which Improves PCB Efficiency and has a Thinner Profile • Pb-Free (RoHS Compliant) Applications • Power Supply Sequencing, Distribution and Control • Hot Swap / Electronic Circuit Breaker Circuits
