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
