LTC4225-2 Datasheet Dual Ideal Diode And Hot Swap Controller

Manufacturer: Linear Technology (now Analog Devices)

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LTC®4225 offers ideal diode and Hot Swap™ functions for two power rails by controlling external series connected N-channel MOSFETs.

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

Hot Swap control MOSFETs allow boards to be safely inserted and removed from a live backplane by limiting inrush current.

Key Features
