Procurement Notes
Verify the specific suffix 'ERTER' against the official Texas Instruments datasheet to confirm the reel packaging quantity and tape specifications. Ensure the ordering part number matches the exact pinout and thermal pad configuration required for your PCB layout. Cross-reference the manufacturer's latest revision history to confirm component availability and any potential form-fit-function changes.
Selection Notes
Select this component when a compact solution for bipolar stepper or dual brushed DC motors is required. It is suitable for applications needing integrated current sensing without external amplifiers. Consider the 16-WQFN package constraints for thermal management and board space. Verify that the input voltage range and current requirements align with the motor specifications before finalizing the design.
Part Context
The DRV8428 belongs to Texas Instruments' family of advanced motor drivers featuring Smart Tune technology. This series integrates power MOSFETs and control logic into a single chip, simplifying the design of motor control systems. The DRV8428 specifically targets applications requiring high precision and efficient current management in a small footprint.
Replacement Considerations
Consult the Texas Instruments DRV8428 datasheet for officially listed alternative part numbers within the same product family. Verify compatibility regarding pin assignments, thermal characteristics, and electrical specifications before substitution.
