LTC4228-2 - Dual Ideal Diode and Hot Swap Controller

Download the LTC4228-2 datasheet PDF. This datasheet also covers the LTC4228-1 variant, as both devices belong to the same dual ideal diode and hot swap controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®4228 offers ideal diode and Hot Swap™ functions for two power rails by controlling two external N-channel MOSFETs in each rail.

MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area.

Key Features
