LM74722-Q1 Datasheet Automotive Low Iq Ideal Diode Controller

Manufacturer: Texas Instruments

Overview: LM74722-Q1 SLVSFR9B – SEPTEMBER 2021 – REVISED AUGUST 2022 LM74722-Q1 Automotive Low IQ Ideal Diode Controller with 200-kHz Active Rectification and Load Dump Protection.

General Description

The LM74722-Q1 ideal diode controller drives and controls external back-to-back N-Channel MOSFETs to emulate an ideal diode rectifier with power path ON and OFF control and overvoltage protection.

The wide input supply of 3 V to 65 V allows protection and control of 12-V and 24-V automotive battery powered ECUs.

The device can withstand and protect the loads from negative supply voltages down to –65 V.
