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
