Overcurrent protection with active current limiting Operating Voltage: DC 6V to 30V Bi-directional control for 1 brushed DC motor, single channel 3.3V and 5V logic level input PWM frequency up to 20kHz (Output frequency is same as input frequency) The MD20A enables bidirectional control of one high-power brushed DC motor from 6V to 30V. With discrete NMOS H-Bridge design, this motor driver is able to support 20Amp continuously without any heatsink.

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).
