Product Details

__

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
