LM74704QDDFRQ1 TI Ideal Diode Controller | TSOT-23-8 | 65V, 4A

Product Overview

The LM74704QDDFRQ1 is a high-voltage ideal diode controller from Texas Instruments, designed to replace Schottky diodes in reverse polarity protection and OR-ing applications. It operates over a wide input voltage range of 3.2V to 65V and can drive an external N-channel MOSFET to emulate a low-loss diode. The device features a low quiescent current of 20 µA (typical) and supports load currents up to 4A. Housed in a compact TSOT-23-8 package, it is ideal for space-constrained automotive and industrial applications.
