LT LTC4252BCMS-2#PBF

热插拔控制器1自动重试

Overview

The LTC4252BCMS-2 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 LTC4252-1/LTC4252A-1 latch off after a circuit breaker fault times out. The LTC4252-2/LTC4252A-2 provide automatic retry after a fault. The LTC4252A-1/LTC4252A-2 feature tight ±1% undervoltage/overvoltage threshold accuracy. The LTC4252BCMS-2 is available in either an 8-pin or 10-pin MSOP, while the LTC4252A is available in the 10-pin MSOP.
