ADI LTC4287AUK#PBF

热插拔控制器2自动重试、故障超时、I²C、锁定故障、OVP、PMBus、SMBus、UVLO

Overview

The LTC4280CUFD Hot Swap™ controller allows a board to be safely inserted and removed from a live backplane. Using an external N-channel pass transistor, board supply voltage and inrush current are ramped up at an adjustable rate. An I2C interface and onboard ADC allow for monitoring of load current, voltage and fault status.

The controller has additional features to interrupt the host when a fault has occurred, notify when output power is good, detect insertion of a load card, and power-up either automatically upon insertion or wait for an I2C command to turn on.
