General Description

The LTC®4253/LTC4253A negative voltage Hot Swap™ controllers allow a board to be safely inserted and removed from a live backplane.

Output current is controlled by three stages of current-limiting: a timed circuit breaker, active current limiting and a fast feedforward path that limits peak current under worst-case catastrophic fault conditions.

The LTC4253/LTC4253A latch off after a circuit fault.
