DRV8703DQRHBTQ1 TI Brushed/Stepper Motor Driver | 32-VQFN (5x5) | 8A, 0.2Ω

Product Overview

The DRV8703DQRHBTQ1 is a fully integrated brushed DC and stepper motor driver from Texas Instruments, designed for automotive and industrial applications. It features dual H-bridge drivers capable of driving up to 8A peak current per channel with a low RDS(on) of 0.2Ω (typical) at 25°C. The device operates from a supply voltage range of 4.5V to 45V, making it suitable for 12V and 24V systems. It includes advanced protection features such as overcurrent, overtemperature, and undervoltage lockout. The 32-VQFN (5x5) package enables compact PCB designs.
