TIDRV8876RGTR
Overview
The DRV8876RGTR is a highly integrated N-channel H-bridge motor driver designed for brushed DC and unipolar stepper motors. It supports a wide load voltage range from 4.5V to 37V and can deliver up to 3.5A of peak output current. The device features integrated current sensing and regulation, eliminating the need for external sense resistors to reduce board space and system cost.
Why Choose This Part
The integrated current sensing and proportional IPROPI output provide real-time load monitoring without the power loss of external shunt resistors. It features spread spectrum clocking to minimize EMI and offers selectable control modes (PMODE) to support various MCU PWM interfaces. Comprehensive protection includes undervoltage lockout, overcurrent protection, and thermal shutdown with a dedicated nFAULT pin.
Applications
Key Specifications
Getting Started
Evaluate the driver using the DRV8876LEVM evaluation module, which provides a hardware platform for testing different control modes. Connect the PWM inputs to a microcontroller like an MSP430 or STM32 and monitor the IPROPI pin with an ADC to implement closed-loop current control. Ensure the thermal pad is properly soldered to a large ground plane to manage heat dissipation during high-current operation.
