The MDD20A enables bidirectional control of two high-power brushed DC motors from 6V to 30V. With full discrete NMOS H-Bridge design, this motor driver is able to support 20Amp continuously for each motor without any heatsink.

We test all our motor drivers by running the motor at full load in our lab and monitor its temperature with thermal camera. This test is carried out until the temperature stops increasing and reaches a stable point (usually achieve in 15 minutes). This way, we can get the true current ratings for all our motor drivers.

The onboard test buttons and motors output LEDs allow functional test of the motor driver in a quick and convenient way without hooking up the host controller.

This motor driver can be controlled with PWM and DIR inputs. With input logic voltage range from 1.8V to 12V, it’s compatible with wide variety of host controller (e.g. Arduino, Raspberry Pi, PLC).(e.g. Arduino, Raspberry Pi, PLC).
