The MD25HV is a high-voltage single-channel bidirectional motor driver for brushed DC motor from 7V to 58V. With a discrete NMOS H-Bridge design, this motor driver is able to support 25Amp continuously without an 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. A Buck regulator which produces 5V output is also available to power the host controller. This is especially useful for high voltage applications where no additional power source nor high voltage buck regulator is needed.

MD25HV can be controlled with PWM and DIR inputs. With input logic voltage ranging from 1.8V to 30V, it’s compatible with a wide variety of host controllers (e.g. Arduino, Raspberry Pi, PLC). If you prefer to control the motor directly without any programming, this motor driver can be controlled from a potentiometer (speed) and a switch (direction) too.
