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. It features a charge pump for driving external N-Channel MOSFETs, regulated current protection and duration, output undervoltage monitoring and reporting, optional latch-off or retry response, and adjustable soft-start.

Features

? Fast Current Regulation amplifier quickly responds to overcurrent fault conditions

? Less than 1μs response Time to Dead Short

? Programmable Current Regulation Level and Duration

? Two Levels of Overcurrent Detection Provide Fast Response to Varying Fault Conditions

? Overcurrent Circuit Breaker and Fault Isolation functions

? Adjustable Current Regulation Threshold as low as 20mV

? Selectable Latch-off or Auto Retry Response to Fault conditions

? 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 Plus Anneal Available (RoHS Compliant)

Applications

? Power Supply Sequencing, Distribution and Control

? Hot Swap/Electronic Breaker Circuits
