LT LTC4222IG#PBF

热交换控制器，监控器2Auto Retry, I²C, Fault Timeout, Latched Fault, SMBus, OVP, UVLO

Overview

The LTC4222IG Hot Swap™ controller allows two power paths to be safely inserted and removed from a live backplane. Using external N-channel pass transistors, board supply voltages and inrush currents are ramped up at an adjustable rate. An I2C interface and on-board ADC allows for monitoring of current, voltage and fault status for each channel.

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.
