DRV8844PWP

Overview

The DRV8844PWP is a dual H-bridge motor driver manufactured by Texas Instruments, designed for driving brushed DC motors, bipolar stepper motors, and solenoids. It features an integrated control and power stage with four half-bridge outputs capable of delivering up to 2.5 A output current per channel. The device operates within a supply voltage range of 8 V to 60 V and supports PWM control interfaces. It is housed in a thermally enhanced 28-pin HTSSOP package (PowerPAD) suitable for surface-mount applications. Key protection features include overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature shutdown.

Feature Summary

• Integrates dual H-bridge drivers with independent control inputs for each half-bridge
• Provides comprehensive protection against overcurrent, short circuits, undervoltage, and overheating
• Supports standard PWM control interface for precise motor speed and direction regulation
• Utilizes a thermally enhanced PowerPAD package to improve heat dissipation

Applications

• Brushed DC motor control in office automation machines
• Bipolar stepper motor driving in printers and scanners
• Solenoid and relay actuation in industrial automation systems
• Gaming machine actuators and robotics applications

Procurement Notes

Verify the specific ordering suffix PWP indicates tube packaging rather than reel packaging when sourcing components. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides valid traceability documentation for automotive or industrial grade parts if required by your application standards.

Selection Notes

Select this component when a dual H-bridge solution is needed for driving two separate loads or one bipolar stepper motor. Consider the 28-pin HTSSOP package size and thermal performance relative to your PCB layout constraints. Evaluate the 60 V maximum supply voltage limit against your system's peak operating conditions to ensure adequate headroom.

Part Context

The DRV8844 belongs to Texas Instruments' family of integrated motor drivers designed for automated equipment. It complements other devices like the DRV8842 and DRV8834 by offering higher voltage tolerance and dual-channel capability. This part is commonly used in applications requiring reliable motion control with built-in safety features, serving as a robust alternative to discrete MOSFET solutions.

Replacement Considerations

The DRV8844PWPR is the same functional device but supplied in tape-and-reel packaging instead of tubes. Verify pin compatibility and thermal characteristics when substituting between packaging types. No direct cross-manufacturer equivalents are confirmed in the provided data.
