LM74703-Q1 Datasheet Ideal Diode Controller

Manufacturer: Texas Instruments

General Description

The LM74703-Q1, LM74704-Q1 is an automotive AEC Q100 qualified ideal diode controller which operates in conjunction with an external N-channel MOSFET as an ideal diode rectifier for low loss reverse polarity protection with a 20-mV forward voltage drop.

The wide supply input range of 3.2 V to 65 V allows control of many popular DC bus voltages such as 12-V, 24-V, and 48-V automotive battery systems.

The 3.2-V input voltage support is particularly well suited for severe cold crank requirements in automotive systems.
