Datasheet	LTC4222 Datasheet

The LTC®4222 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 onboard ADC allows for monitoring of current, voltage and fault status for each channel.
