Overview
The DRV8428EPWPR is a dual H-bridge motor driver manufactured by Texas Instruments, designed for bipolar stepper and dual brushed DC motors. It features an integrated power MOSFET architecture with a supply voltage range of 4.5 V to 33 V and a maximum output current of 1 A per bridge. The device supports step/dir interfaces and offers microstepping resolution greater than 256 steps. Operating temperatures range from -40°C to +125°C in a 16-PowerTSSOP package.
Feature Summary
- Integrated current sensing capability for precise motor control
- Smart Tune technology for automatic optimization of motor performance
- Full integration of control logic and power stage in a single IC
Applications
- Bipolar stepper motor control systems
- Dual brushed DC motor drive applications
- General purpose motion control circuits
Procurement Notes
Verify the specific suffix EPWPR against official datasheets to confirm the 16-PowerTSSOP package and commercial temperature grade. Ensure compatibility with system voltage limits not exceeding 33 V. Confirm interface requirements match the STEP/DIR protocol supported by this component variant.
Selection Notes
Select this component when a compact solution for bipolar stepper or dual brushed DC motors is required. It is suitable for designs needing integrated current sensing and high microstepping resolution. Consider the 16-PowerTSSOP package constraints and thermal management requirements for the specified operating temperature range.
Part Context
This part belongs to the DRV8428 family of dual H-bridge drivers from Texas Instruments. It shares core functionalities like Smart Tune and integrated current sense with other variants such as the DRV8428E and DRV8428P series, differing primarily in packaging and specific electrical characteristics defined by the suffix.
Replacement Considerations
Direct substitutes include DRV8428E and DRV8428P series components. Verify pinout compatibility and ensure the replacement matches the required package type and voltage specifications before implementation.
