LM74720QDRRRQ1 TI Ideal Diode Controller | 12-WSON(3x3) | 65V, 5A

Product Overview

The LM74720QDRRRQ1 is a automotive-grade ideal diode controller from Texas Instruments, designed to replace Schottky diodes in reverse polarity protection and OR-ing applications. It features an ultra-low quiescent current of 1.5 µA (typical) and supports input voltages from 3.2 V to 65 V. The device drives an external N-channel MOSFET to emulate a diode with very low forward voltage drop, minimizing power dissipation and heat. Housed in a compact 12-WSON (3x3 mm) package, it is AEC-Q100 qualified for automotive applications.
