The DRV8837CDSGR is a brushed DC motor driver developed by Texas Instruments. Designed for space-constrained and battery-operated applications, it delivers a compact and efficient solution for controlling small motors. With a wide voltage range (2V to 11V) and up to 1.8A peak output current, it is ideal for applications like robotics, toys, portable electronics, and camera systems.
How Does DRV8837CDSGR Work?
The DRV8837CDSGR operates in an H-Bridge configuration, allowing full bidirectional control of a single DC motor. It integrates low R<sub>DS(on)</sub> MOSFETs for efficient switching and thermal performance. It supports PWM (pulse-width modulation) control and offers built-in protection features including overcurrent protection, thermal shutdown, and undervoltage lockout.
How Many Pins Does DRV8837CDSGR Have and What Are the Functions of the Pinout Configuration?
The DRV8837CDSGR comes in an 8-pin WSON (2mm x 2mm) package. Its pinout includes:
VM: Motor power supply input
GND: Ground
OUT1 / OUT2: Motor driver outputs
IN1 / IN2: Control inputs for H-Bridge logic
nSLEEP: Logic input to enable/disable the device
VCC: Logic power supply
PAD: Thermal pad (must be connected to GND)
