DRV8876PWPR

Overview

The DRV8876PWPR is a brushed DC motor driver from Texas Instruments, housed in a 16-pin HTSSOP package. It operates on a single supply voltage ranging from 4.5 V to 37 V. The device integrates two half-bridges capable of delivering a peak output current of 3.5 A. Key electrical parameters include an on-resistance (HS + LS) of 700 mOhms and a quiescent supply current of 3 mA. It supports multiple control interfaces including PWM, PH/EN, and independent half-bridge modes. The component functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates current sensing with a dedicated current sense output for load monitoring without external high-power resistors.
• Supports flexible control via PWM, PH/EN, or independent half-bridge configurations for driving electromagnetic loads.
• Features integrated hardware management interface for simplified controller connection.

Applications

• Industrial brushed DC motor control
• Automotive motion systems
• Electromagnetic load driving

Procurement Notes

Verify the specific package variant, as the DRV8876 series includes both HTSSOP and VQFN options. Confirm that the required current rating aligns with the 3.5 A limit. Ensure the system voltage does not exceed the 37 V maximum. Check for moisture sensitivity requirements during storage and handling. Validate compatibility with the intended control interface signals.

Selection Notes

Select this component when a compact solution for low-to-medium power brushed DC motors is required. It is suitable for applications needing integrated current feedback to simplify design. Consider the HTSSOP package for through-hole or surface mount flexibility depending on board layout. Evaluate thermal performance if operating near the peak current limits.

Part Context

This part belongs to the DRV8876 family of motor drivers designed for industrial and automotive use. It complements higher-current variants like the DRV8873 by offering a lower current capacity in a similar form factor. The family emphasizes ease of integration through built-in protection and sensing features.

FAQ

Does the DRV8876PWPR support independent half-bridge control?

Yes, the device allows for independent control of each half-bridge, enabling the driving of two separate electromagnetic loads.

How is current sensing implemented in this driver?

It uses an internal current mirror to detect current near the high-side FET, providing a scaled output signal without requiring external shunt resistors.
