LTC4222 Datasheet (Linear Technology) - Dual Hot Swap Controller

LTC4222, Dual Hot Swap Controller

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 curren
