LTC4215-1 Datasheet (Linear Technology)

LTC4215-1, Hot Swap Controller

The LTC®4215-1/LTC4215-3 Hot Swap™ controllers allow 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 loa
