DRV8426PRGER

Overview

The DRV8426PRGER is a dual H-bridge motor driver from Texas Instruments, designed for bipolar stepper motors and dual bidirectional brushed-DC motors. It operates within a supply voltage range of 4.5 V to 33 V. The device features integrated current sense functionality with ±5% full-scale accuracy, eliminating the need for external sense resistors. It supports multiple control interfaces including phase/enable and PWM. The component offers Smart Tune technology with fast and mixed decay options, configurable off-time PWM chopping, and low RDS(on) characteristics.

Feature Summary

• Integrated current sense functionality eliminates the requirement for external sense resistors while maintaining high accuracy.
• Smart Tune technology provides adjustable fast and mixed decay modes for optimized motor performance.
• Supports multiple control interface options including phase/enable and PWM input configurations.
• Configurable off-time PWM chopping allows flexibility in current regulation and thermal management.

Applications

• Bipolar stepper motor control
• Dual bidirectional brushed-DC motor drives
• Four unidirectional brushed-DC motor systems

Procurement Notes

Verify the specific suffix PRGER against the official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating voltage range and control interface signals. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before finalizing procurement.

Selection Notes

Select this component when a dual H-bridge solution is needed for either one bipolar stepper or two bidirectional DC motors. It is suitable for applications requiring integrated current sensing without external shunts. Consider its 33-V maximum rating and 1.5-A full-scale stepper current capacity relative to load requirements.

Part Context

This part belongs to the DRV8426E/P family of dual H-bridge motor drivers. It is pin-to-pin compatible with other variants such as the DRV8424E/P, DRV8436E/P, and DRV8434E/P, which offer different voltage ratings and on-resistance characteristics. This integration simplifies design reuse across different motor drive power levels.

Replacement Considerations

Pin-compatible alternatives include DRV8424E/P, DRV8436E/P, and DRV8434E/P. Verify that the substitute part meets the specific voltage and current requirements of the application, as these variants differ in maximum supply voltage and bridge resistance.
