Overview
The DRV8424PPWPR is a bipolar stepper motor driver from Texas Instruments, housed in an HTSSOP-28 package. It supports a supply voltage range of 4.5 V to 33 V and delivers up to 2.5 A output current. The device operates within a temperature range of -40°C to +125°C with a quiescent supply current of 5 mA. It features integrated protections including overcurrent, thermal shutdown, and under-voltage lockout.
Feature Summary
- Integrated half-bridge driver architecture for bipolar stepper motors
- Built-in thermal shutdown and overcurrent protection mechanisms
- Supports microstepping resolutions via step/dir interface
Applications
- Bipolar stepper motor control systems
- Dual brushed DC motor drivers
- Industrial automation motion control
- Medical equipment actuation
Procurement Notes
Verify the specific suffix PPWPR against the official datasheet to confirm the HTSSOP-28 package and reel packaging configuration. Ensure compatibility with the target application's voltage and current requirements before procurement. Confirm RoHS compliance status through the manufacturer's documentation.
Selection Notes
Select this component when a robust stepper driver with high current capability and wide operating temperature range is required. Consider the HTSSOP-28 package for surface-mount assembly constraints. Evaluate thermal management needs due to the 2.5 A output capacity and ensure the system design accommodates the specified voltage limits.
Part Context
This part belongs to the DRV8424E series of motor controllers. It is designed for applications requiring reliable stepper motor control with integrated safety features. The series offers various package options to suit different PCB layout requirements while maintaining consistent electrical performance characteristics across the family.
Replacement Considerations
The DRV8424PRGER is a verified substitute within the same series, offering identical electrical specifications but differing in factory packaging quantity and potentially reel specifications. Verify pin-to-pin compatibility and thermal performance before substitution.
