TIDRV8876PWPR
Overview
The DRV8876PWPR is a highly integrated N-channel H-bridge motor driver designed for brushed DC motors with a load voltage range of 4.5V to 37V. It features integrated current sensing and regulation, eliminating the need for external sense resistors to reduce board space and system cost. The device supports various control modes including PWM and PH/EN, making it versatile for different MCU architectures.
Why Choose This Part
This driver significantly reduces BOM count by integrating current sensing and a proportional current output (IPROPI). It offers flexible control via selectable PMODE and IMODE settings, allowing engineers to switch between PWM, PH/EN, or independent half-bridge modes without changing hardware. Built-in spread spectrum clocking also helps designers meet strict EMI requirements.
Applications
Key Specifications
Getting Started
Engineers should start by evaluating the DRV8876EVM evaluation module to test different current regulation modes. Connect the logic pins to a microcontroller like an MSP430 or STM32, ensuring the nSLEEP pin is pulled high to wake the device. Configure the PMODE pin to match your preferred MCU control scheme (Phase/Enable or PWM) and monitor nFAULT for real-time diagnostic feedback.
