TIDRV8873SPWPRQ1
Overview
The DRV8873SPWPRQ1 is an AEC-Q100 qualified integrated H-bridge driver designed for automotive brushed DC motor control. It supports a wide load voltage range from 4.5V to 38V and can deliver up to 10A of peak output current. The device features an SPI interface for advanced configuration and diagnostics, alongside integrated current sensing that eliminates the need for external shunt resistors.
Why Choose This Part
This driver integrates power NMOS FETs and current sensing into a single HTSSOP package, significantly reducing PCB footprint. It includes spread spectrum clocking to minimize electromagnetic interference (EMI) and offers a programmable SPI interface for fine-tuning protection thresholds and PWM modes.
Applications
Key Specifications
Getting Started
To evaluate this part, use the DRV8873S-Q1EVM evaluation module which allows for easy testing of the SPI registers and motor performance. Interface the driver with a microcontroller using standard 4-wire SPI and ensure the thermal pad is properly soldered to a large ground plane to manage the 10A peak current capability.
