DRV8876NPWPR

Overview

The DRV8876NPWPR is a half-bridge brushed DC motor driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 37 V and supports a continuous output current of 3.5 A. The device features an integrated current sense amplifier with a dedicated output pin for monitoring. It utilizes a 16-pin HTSSOP package and functions at switching frequencies up to 100 kHz. The component is rated for operation in temperatures ranging from -40°C to +125°C, with a typical quiescent current of 3 mA.

Feature Summary

• Integrated current sense amplifier providing a dedicated output signal for real-time load monitoring
• Hardware management interface supporting PWM, phase/enable, and independent half-bridge control modes
• Built-in protection mechanisms including thermal shutdown and undervoltage lockout

Applications

• Brushed DC motor control in industrial automation systems
• Motion control circuits for office equipment such as printers and scanners
• Battery-powered appliance motor drivers

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-16 package and reel packaging configuration required for your assembly process. Confirm that the design accommodates the specified 37 V maximum supply voltage and 3.5 A current limits under all operating conditions. Ensure compatibility with the 100 kHz switching frequency regarding external component selection.

Selection Notes

Select this component when a single half-bridge solution with integrated current sensing is required for low-to-medium power brushed DC motors. It is suitable for designs needing hardware-based fault management and multiple control interfaces. Consider alternative packages or higher current ratings if the application exceeds 3.5 A or requires different thermal performance characteristics.

Part Context

This part belongs to the DRV8876N series of motor drivers from Texas Instruments. It is distinct from the DRV8876PWPR variant primarily by its specific package and tape-and-reel configuration. The series is designed for cost-sensitive applications requiring reliable motor control with minimal external components.

Replacement Considerations

The DRV8876PWPT is a related variant within the same family offering similar electrical specifications but potentially different packaging options.
