LM74670QDGKRQ1 Description

Short technical summary and product information.

The Texas Instruments LM74670QDGKRQ1 is an automotive-grade ideal diode rectifier controller designed for efficient power management. It supports an input voltage range from 0.48V to 42V, with a maximum current handling capability of 250A.

 

This device features a zero IQ charge pump gate driver for an external N-channel MOSFET, enabling low forward voltage drop and reduced power dissipation compared to traditional Schottky diodes. It is capable of handling AC signals up to 300 Hz.

 

The LM74670QDGKRQ1 operates within an ambient temperature range of -40°C to 125°C and is qualified to AEC-Q100 Grade 1 standards. It is available in an 8-VSSOP package, suitable for surface mount applications.

 

Key features include automotive load dump compatibility, linear control, reverse current blocking, and reverse polarity protection, making it suitable for general-purpose applications requiring robust power protection.
