DRV8313PWPR Triple 1/2-H Bridge Driver: Specs, Design Guide, and Alternatives

Quick Answers: What Is the DRV8313PWPR and What Are Its Key Verified Specs?

The Texas Instruments DRV8313PWPR is a triple 1/2-H bridge driver designed for three-phase brushless-DC motors and other inductive loads. It delivers up to 2.5 A continuous output current per channel (3 A peak) and operates from a supply voltage range of 8 V to 60 V. The device is housed in a 28-pin HTSSOP (PWP) package and is currently in active lifecycle status with 99,999 units in stock at XAIPART, priced at $2.7045 per unit at 1,000+ quantity (as of 2026-08-27).

This driver integrates N-channel power MOSFETs in a half-bridge configuration, providing three independent outputs that can be controlled via a simple PWM interface. It includes overcurrent, overtemperature, and undervoltage lockout protection, plus a low-power sleep mode. The wide voltage range and current capability make it suitable for 12 V and 24 V systems in industrial, automotive, and consumer applications.

Technical Guide: How to Select, Design In, and Use the DRV8313PWPR

Understanding the DRV8313PWPR Architecture

The DRV8313PWPR contains three independent 1/2-H bridge outputs, each capable of sourcing or sinking current. This configuration is ideal for driving three-phase brushless-DC motors, where each phase connects to one half-bridge. The device also supports independent control of each half-bridge, allowing it to drive solenoids, relays, or other loads.

Designing with the DRV8313PWPR

When designing with the DRV8313PWPR, ensure adequate PCB copper area for heat dissipation, especially at high currents. The exposed thermal pad should be soldered to a large ground plane to improve thermal performance. Place decoupling capacitors close to the power supply pins (VM) to minimize voltage transients.

The device uses a simple PWM interface, allowing direct connection to a microcontroller's PWM outputs. Each half-bridge can be controlled independently, enabling flexible motor control schemes such as trapezoidal or sinusoidal commutation. The current sense output can be used for closed-loop current control, enhancing system performance.
