Looking for a motor driver for your mobile robot? Want to drive a stepper motor? Worry not! MDD3A is able to control two brushed DC motors or single bipolar/unipolar stepper motor from 4V to 16V. With discrete MOSFETs H-Bridge design, this motor driver is able to support 3 Amp per channel continuously without any additional heatsink.
The onboard test buttons and motor output LEDs allow functional testing of the motor driver in a quick and convenient way without hooking up the host controller. Buck-boost regulator which produces 5V output from input as low as 4V can be used to power the host controller.
MDD3A can be controlled with wide input logic voltage ranging from 1.8V to 12V; it’s also compatible with wide variety of host controllers (e.g. Arduino, Raspberry Pi, PLC).
To prevent the motor driver from being damaged by reverse voltage if the battery is connected in wrong polarity, it is equipped with reverse polarity protection.
Example Application: Small size mobile robot for competition or school projects.
