Description

General part information

LTC4222 Series

The LTC4222 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 device features adjustable, analog, foldback current limit circuits and a Soft-Start circuit that sets the dI/dt of the inrush currents. An I2C interface may configure the part to latch off or automatically restart after the LTC4222 detects a fault on either 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.ApplicationsLive Board InsertionElectronic Circuit BreakersComputers, ServersPlatform Management
