Description

General part information

LTC4229 Series

The LTC4229 offers ideal diode and Hot Swap™functions for a power rail by controlling two external N-channel MOSFETs. The MOSFET acting as an ideal diode replaces a high power Schottky diode and the associated heat sink, saving power and board area. The Hot Swap MOSFET control allows a board 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 foldback current limit and electronic circuit breaker.The LTC4229 regulates the forward voltage drop across the external MOSFET to ensure smooth current transfer in diode-OR applications. The ideal diode turns on quickly to reduce the load voltage droop during supply switchover. If the input supply fails or is shorted, a fast turn-off minimizes reverse-current transients.The LTC4229 provides adjustable start-up delay, undervoltage and overvoltage protection, and reports fault and power good status for the supply. It can be configured for latch off or automatic retry after a fault.ApplicationsRedundant Power SuppliesSupply HoldupHigh Availability Systems and ServersTelecom and Network InfrastructurePower Prioritizer
