UC3770BN TI Motor Driver | 16-PDIP | 1.5A Output, 36V Supply

Product Overview

The UC3770BN is a bipolar stepper motor driver IC from Texas Instruments, designed for precise control of two-phase stepper motors. It integrates a constant-current chopper drive and a translator, simplifying the interface to a step and direction input. The device operates from a supply voltage up to 36V and can deliver up to 1.5A per winding. Housed in a 16-pin PDIP package, it is suitable for a wide range of industrial and consumer applications requiring reliable stepper motor control.
