DRV8426EPWPR TI Stepper Motor Driver | 28-HTSSOP | 2.5A, 4.5-33V

Product Overview

The DRV8426EPWPR is a dual-bridge motor driver from Texas Instruments, designed for driving two stepper motors or four brushed DC motors. It integrates N-channel power MOSFETs with a low RDS(on) of 0.5Ω 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 per bridge. It features advanced current regulation, microstepping for stepper motors, and protection functions including overcurrent, overtemperature, and undervoltage lockout. The 28-HTSSOP package with PowerPAD ensures excellent thermal performance.
