LTC4225-2 - Dual Ideal Diode and Hot Swap Controller

This page provides the datasheet information for the LTC4225-2, a member of the LTC4225-1 Dual Ideal Diode and Hot Swap Controller family.

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.
