Product Introduction

Overview

The DRV104PWPRG4, produced by Texas Instruments, is a high-side DMOS power switch that utilizes a pulse-width modulated (PWM) output. This device is designed to drive electromechanical and thermal devices such as solenoids, valves, relays, actuators, heaters, and lamps. The DRV104 features adjustable PWM output, allowing for fine control over the power delivered to the load, which enhances reliability and reduces heat rise. It operates over a wide supply range of +8V to +32V and is optimized for applications requiring both high initial pull-in current and lower continuous hold current.
