DRV8844PWPR

Overview

The DRV8844PWPR is a dual H-bridge motor driver manufactured by Texas Instruments, designed for driving bipolar stepper motors and brushed DC motors. It operates within a supply voltage range of 8V to 60V and delivers an output current of up to 2.5A per channel. The device integrates power MOSFETs in a half-bridge configuration with four independent outputs. It utilizes a parallel interface for control signals and functions within a junction temperature range of -40°C to +150°C. The component is housed in a 28-pin HTSSOP package.

Feature Summary

• Integrates four half-bridge drivers capable of controlling two bipolar stepper motors or two brushed DC motors simultaneously.
• Features a fully integrated design combining control logic and power stages to minimize external component requirements.
• Supports high thermal performance with a wide operating junction temperature range suitable for demanding environments.

Applications

• Bipolar stepper motor control systems
• Brushed DC motor drive applications
• General-purpose motion control circuits

Procurement Notes

Verify the specific suffix 'G4' if RoHS compliance is required, as standard versions may differ. Confirm moisture sensitivity level (MSL 3) handling procedures during assembly. Ensure the HTSSOP-28 footprint matches the PCB layout specifications provided in the official datasheet. Cross-reference the manufacturer part number with distributor listings to confirm availability status and lead times.

Selection Notes

Select this component when a dual H-bridge solution is needed for voltages up to 60V. Consider the 2.5A continuous current rating against load requirements. Evaluate the 28-pin HTSSOP package size constraints relative to board space. Verify that the parallel interface logic levels are compatible with the host microcontroller or controller IC being used in the system design.

Part Context

This part belongs to the DRV8844 family of motor drivers from Texas Instruments. It is distinct from similar models like the DRV8847 or DRV8846 by its specific voltage range and current capabilities. The PWPR suffix indicates the tube packaging variant available through distributors, while the G4 suffix denotes environmental compliance features.

Replacement Considerations

The DRV8844PWP is the tube-packaged equivalent of this reel-part. Check for pin-to-pin compatibility with other dual H-bridge drivers in the same voltage class if sourcing alternatives.
