LTC4412 Datasheet (Linear Technology) - Low Loss PowerPath Controller

LTC4412, Low Loss PowerPath Controller

The LTC®4412 controls an external P-channel MOSFET to create a near ideal diode function for power switchover or load sharing.

This permits highly efficient OR’ing of multiple power sources for extended battery life and low self-heating.

When conducting, the voltage drop across the MOSFET is typical
