DRV8845RHHR TI Stepper Motor Driver | 36-VQFN (6x6) | 2.5A, 8.2V to 45V

Product Overview

The DRV8845RHHR from Texas Instruments is a highly integrated stepper motor driver IC designed for bipolar stepper motors. It features dual H-bridge drivers capable of driving up to 2.5 A per winding (with proper heat sinking) and operates from a supply voltage range of 8.2 V to 45 V. The device includes advanced current regulation, microstepping up to 1/32 step, and protection features such as overcurrent, overtemperature, and undervoltage lockout. Housed in a compact 36-pin VQFN (6x6 mm) package, it is ideal for space-constrained applications requiring precise motor control.
