Overview
The DRV8425PPWPR is a dual H-bridge stepper motor driver from Texas Instruments, designed for bipolar stepper motors and dual brushed DC applications. It features an integrated current sense amplifier with smart tune technology for simplified tuning. The device supports microstepping resolutions up to 1/256 step via a simple STEP/DIR interface. Key electrical parameters include a supply voltage range of 4.5 V to 35 V and a maximum output current of 2 A per bridge. It operates within a temperature range of -40°C to +125°C and is housed in a 28-pin HTSSOP package.
Feature Summary
- Integrates current sense amplifiers with smart tune technology to simplify motor tuning and reduce external component count.
- Supports high-resolution microstepping up to 1/256 step mode for smooth motion control.
- Features a standard STEP/DIR interface for easy integration with controller circuits.
Applications
- Bipolar stepper motor control in automation equipment
- Dual brushed DC motor drive systems
- Precision positioning mechanisms requiring fine microstepping
Procurement Notes
Verify the complete part number including suffix PPWPR to ensure correct packaging and temperature grade. Confirm that the application design accounts for thermal dissipation requirements associated with the HTSSOP-28 package under expected load conditions. Ensure compatibility with the 4.5 V to 35 V supply voltage range specified in the datasheet.
Selection Notes
Select this component when high-resolution microstepping up to 1/256 is required alongside integrated current sensing capabilities. It is suitable for designs needing a compact solution for bipolar stepper or dual brushed DC motors within a 35 V system. Consider the thermal performance of the HTSSOP-28 package relative to the expected continuous current load.
Part Context
This device belongs to the DRV8424E/P and DRV8425E/P family of dual H-bridge motor drivers. These components are engineered to provide integrated solutions for stepper and brushed DC motor applications, combining power stage drivers with control logic and current sensing in a single package.
Replacement Considerations
The DRV8424PPWPR is a related variant within the same family, offering similar functionality but potentially differing in specific current ratings or feature sets. Verify pin-to-pin compatibility and electrical specifications before substitution.
