LTC4228-2
Overview
The LTC®4228 offers ideal diode and Hot Swap™ functions for two power rails by controlling two external N-channel MOSFETs in each rail. MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area.
- Power Path and Inrush Current Control for Redundant Supplies
- Low Loss Replacement for Power Schottky Diodes
- Protects Output Voltage from Input Brownouts
- Allows Safe Hot Swapping from a Live Backplane
- 2.9V to 18V Operating Range
- Controls N-Channel MOSFETs
- Limits Peak Fault Current in ≤1µs
- Adjustable Current Limit with Circuit Breaker
- Adjustable Current Limit Fault Delay
- Smooth Switchover without Oscillation
