TIDRV8872DDAR
Overview
The DRV8872DDAR is a brushed DC motor driver featuring an integrated H-bridge and current regulation for applications operating between 6.5V and 45V. It can deliver up to 3.6A of peak output current and includes a low-power sleep mode that reduces current consumption to 10uA. The device is designed to handle a single bipolar stepper motor or a brushed DC motor using a simple PWM interface.
Why Choose This Part
The DRV8872DDAR simplifies design by integrating current sensing and regulation, eliminating the need for external sense resistors in many applications. It features a dedicated nFAULT pin for real-time diagnostics and automatic fault recovery for overcurrent and thermal events. The HSOP-8 PowerPad package provides excellent thermal dissipation, allowing for high current delivery in a small footprint.
Applications
Key Specifications
Getting Started
To evaluate the DRV8872DDAR, start with the DRV8872EVM evaluation module which provides a complete reference layout and terminal blocks for motor connections. Connect a PWM signal from any MCU to the IN1 and IN2 pins to control direction and speed. Ensure the PowerPad is soldered to a large ground plane on the PCB to manage thermal performance during high-current operation.
