Overview
The DRV8425EPWPR is a dual H-bridge motor driver manufactured by Texas Instruments, designed for bipolar stepper motors and dual brushed DC applications. It operates within a supply voltage range of 4.5 V to 35 V and delivers an output current of up to 2 A per bridge. The device features a STEP/DIR interface and supports microstepping resolutions up to 1/256. It incorporates integrated current sense amplifiers for precise control and includes Smart Tune technology for automatic optimization.
Feature Summary
- Integrated current sense amplifiers enable precise open-loop current regulation without external shunt resistors.
- Smart Tune technology automatically optimizes chopper parameters for improved efficiency and reduced acoustic noise.
- Supports high-resolution microstepping up to 1/256 for smooth motion control and reduced resonance.
Applications
- Bipolar stepper motor positioning systems
- Dual brushed DC motor control in industrial automation
- Precision motion control modules requiring low acoustic noise
Procurement Notes
Verify the specific suffix EPWPR against the official datasheet to confirm package type and temperature rating. Ensure compatibility with the target system's logic voltage levels and thermal management requirements before procurement.
Selection Notes
Select this component when a dual H-bridge solution is required for driving two independent brushed DC motors or one bipolar stepper motor. It is suitable for applications needing integrated current sensing and programmable microstepping capabilities within a compact HTSSOP package.
Part Context
This part belongs to the DRV842x family of stepper drivers from Texas Instruments. It shares functional similarities with the DRV8424 but offers enhanced performance characteristics. The family is designed to simplify motor control designs by integrating power stages and control logic into a single chip.
Replacement Considerations
Direct substitutes include DRV8425E, DRV8425P, DRV8425ERGER, and DRV8425PPWPR. Verify pinout compatibility and electrical specifications before substitution.
