Description

General part information

LTC4225-1LTC4225-2 Series

The LTC4225 offers ideal diode and Hot Swap™functions for two power rails by controlling external series connected N-channel MOSFETs. MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area. Hot Swap control MOSFETs allow boards to be safely inserted and removed from a live backplane by limiting inrush current. The supply output is also protected against short-circuit faults with a fast acting current limit and internal timed circuit breaker.The LTC4225 regulates the forward voltage drop across the back-to-back MOSFETs to ensure smooth current transfer from one supply to the other without oscillation. The ideal diodes turn on quickly to reduce the load voltage droop during supply switch-over. If the input supply fails or is shorted, a fast turn-off minimizes reverse-current transients.The LTC4225 allows independent on/off control, and reports fault and power good status for the supply. The LTC4225-1 features a latch-off circuit breaker, while the LTC4225-2 provides automatic retry after a fault.ApplicationsRedundant Power SuppliesSupply HoldupMicroTCA Systems and ServersTelecom NetworksPower Prioritizer
