The MDD20A enables bidirectional control of two high-power brushed DC motors from 6V to 30V. With a full discrete NMOS H-Bridge design, this motor driver is able to support 20Amp continuously for each motor without any heatsink.
A lot of motor drivers in the market specify their current ratings according to the MOSFET specifications. This is highly inaccurate and overrated because the actual current capability is dependent on many other factors such as switching frequency, heatsink efficiency, PCB size, copper thickness and etc.
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 a wide variety of host controllers. Various protection features are also incorporated in each channel of the MDD20A. Overcurrent protection prevents the motor driver from damage when the motor stalls or an oversized motor is hooked up. When the motor is trying to draw a current more than what the motor driver can support, the motor current will be limited at the maximum threshold.
