General Description

The LTC®4253B negative voltage Hot Swap™ controller allows 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 LTC4253B latches off after a circuit fault.

Overview
