DRV8847PWPR

Overview

The DRV8847PWPR is a dual H-bridge motor driver from Texas Instruments, designed for controlling bipolar stepper motors and brushed DC motors. It integrates power MOSFETs in a 16-HTSSOP package. The device operates with a supply voltage range of 2.7 V to 18 V and supports an output current of 2 A per channel. It features PWM interface control and includes thermal shutdown protection. The component functions as a fully integrated controller and power stage, suitable for general-purpose motion control applications within a temperature range of -40°C to +150°C (junction).

Feature Summary

• Integrates dual half-bridge outputs for independent motor control.
• Supports both bipolar stepper and brushed DC motor types.
• Includes built-in thermal shutdown for overtemperature protection.

Applications

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

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-16 package and reel packaging configuration. Confirm that the required operating voltage and current ratings align with the target motor specifications. Ensure compatibility with the intended PWM control interface. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a compact dual H-bridge solution is required for low-to-medium power motor applications. The integrated design reduces external component count compared to discrete solutions. Consider the thermal performance limits and junction temperature rating for high-duty cycle operations. Evaluate the 16-pin footprint against available PCB space constraints.

Part Context

This part belongs to the DRV8847 series of motor drivers. It shares functional similarities with other variants like DRV8847PWR and DRV8847SPWR, differing primarily in package type and manufacturing revision. The PWPR designation indicates a specific tape-and-reel packaging format for automated assembly.

Replacement Considerations

Direct substitutes include DRV8847PWR and DRV8847SPWR, provided the package difference (HTSSOP vs TSSOP) is acceptable. Cross-reference pinouts and thermal characteristics before substitution.
