TIDRV8837DSGR
Overview
The DRV8837DSGR is an ultra-compact H-bridge motor driver designed to control one brushed DC motor or other inductive loads like solenoids. It operates with a motor power supply (VM) up to 11V and a logic supply (VCC) from 1.8V to 7V, making it ideal for battery-powered systems. The device provides a simple PWM (IN1/IN2) interface and can deliver up to 1.8A of output current.
Why Choose This Part
The primary advantage is the tiny 2mm x 2mm WSON package, which significantly reduces PCB footprint compared to SOIC drivers. It features low MOSFET on-resistance and a dedicated nSLEEP pin that drops current consumption to a mere 95uA (typical) to extend battery life. Integrated protection features like overcurrent, thermal shutdown, and undervoltage lockout ensure robust operation without external monitoring components.
Applications
Key Specifications
Getting Started
To evaluate the driver, the DRV8837EVM evaluation module provides a pre-assembled platform with headers for easy interfacing with microcontrollers like an MSP430 or Arduino. Ensure a 0.1uF ceramic bypass capacitor is placed close to the VM and VCC pins for stability. Control logic requires two PWM signals to manage direction and speed through the IN1 and IN2 pins.
