Product Image Gallery:

Texas Instruments’ DRV8833 is a dual H-bridge motor driver IC that can be used for bidirectional control of two brushed DC motors at 2.7 to 10.8 V. It can supply up to about 1.2 A per channel continuously and can tolerate peak currents up to 2 A per channel for a few seconds, making it an ideal driver for small motors that run on relatively low voltages.

WARNING:

This product can get hot enough to burn you long before the chip overheats. Take care when handling this product and other components connected to it!

Specifications:

  • Operating voltage: 2.7‌‌–10.8 V
  • Output current: 1.2 A continuous (2 A peak) per motor
  • Motor outputs can be paralleled to deliver 2.4 A continuous (4 A peak) to a single motor
  • 3 V compatible inputs
  • Undervoltage, overcurrent, and thermal shutdown
  • Reverse-voltage protection circuit
  • Current limiting can be enabled by adding sense resistors (not included)

Current limiting:
 
The DRV8833 can actively limit the current through the motors by using a fixed-frequency PWM current regulation (current chopping). By default, this carrier board connects the current sense pins to ground, disabling the current limiting feature. To enable current limiting, you can use a knife to cut the break points on the back of the board and then solder some appropriate current sense resistors to the unpopulated pads on the front, as indicated in the image below. The pads are sized for 1206 surface-mount resistors. Refer to the DRV8833 datasheet for information on how the resistor value determines the chopping current.
