UC3770BN

Overview

The UC3770BN is a high-performance stepper motor controller and driver manufactured by Texas Instruments. It features a full-bridge output configuration capable of delivering up to 2 A of output current. The device operates within a supply voltage range of 10 V to 45 V and draws a typical operating supply current of 33 mA. Designed for through-hole mounting, it is housed in a PDIP-16 package. The component supports an operating temperature range from 0°C to +70°C and includes one output channel.

Feature Summary

• Integrates a full-bridge driver topology for direct stepper motor control
• Supports bipolar stepper motor applications with dedicated drive circuitry
• Provides robust output current capability for standard stepper loads

Applications

• Bipolar stepper motor control systems
• Motion control circuits requiring integrated driving
• Industrial automation equipment utilizing stepper actuators

Procurement Notes

Verify the specific suffix 'BN' against the manufacturer's official datasheet to confirm the commercial grade temperature rating and packaging specifications. Ensure the procurement source provides valid traceability documentation. Confirm that the PDIP-16 through-hole package aligns with the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a single-chip solution for bipolar stepper motors is required. It is suitable for designs needing a full-bridge driver with moderate current capacity. Consider the PDIP-16 package for through-hole assembly processes. Evaluate the 10 V to 45 V supply range compatibility with the system power architecture.
