LTC4282 Datasheet High Current Hot Swap Controller

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC4282 High Current Hot Swap Controller with I2C Compatible.

General Description

The LTC®4282 hot swap controller allows a board to be safely inserted and removed from a live backplane.

Using one or more external N-channel pass transistors, board supply voltage and inrush current are ramped up at an adjustable rate.

An I2C interface and onboard ADC allows for monitoring of board current, voltage, power, energy and fault status.

Key Features

  • n Allows Safe Board Insertion Into Live Backplane n 12-/16-Bit ADC with ±0.7% Total Unadjusted Error n Monitors Current, Voltage, Power and Energy n Controls Two Parallel N-Channel MOSFETs for SOA Sharing in High Current.
