LM74501QDDFRQ1 TI Ideal Diode Controller | TSOT-23-8 | 3.2V-65V, 1.5A

Product Overview

The LM74501QDDFRQ1 is a high-voltage ideal diode controller from Texas Instruments, designed for reverse polarity protection and OR-ing applications. It integrates a N-channel MOSFET driver to emulate a Schottky diode with significantly lower forward voltage drop and power dissipation. The device operates over a wide input voltage range of 3.2V to 65V and can handle continuous currents up to 1.5A. Housed in a compact TSOT-23-8 package, it is ideal for space-constrained automotive and industrial applications.
