DRV8424EPWPR TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 4.5-33V

Product Overview

The DRV8424EPWPR is a dual-bridge motor driver from Texas Instruments, designed for bipolar stepper motors or dual brushed DC motors. It integrates N-channel power MOSFETs with a low RDS(on) of 0.5Ω (typical) per FET, enabling high efficiency and compact design. The device operates from a supply voltage range of 4.5V to 33V and can deliver up to 2.5A peak current per bridge. It features advanced current regulation, microstepping capability up to 1/256 step, and protection functions including overcurrent, overtemperature, and undervoltage lockout. The 28-HTSSOP package with exposed thermal pad ensures excellent thermal performance.
