## Overview

The Cytron MD20A is a robust 20A continuous, bi-directional DC motor driver supporting 6V to 30V input voltage. Designed with a discrete NMOS H-Bridge, it delivers high-efficiency motor control compatible with a wide range of logic levels (1.8V to 12V). Featuring PWM control up to 20kHz and built-in protections like overcurrent limiting and temperature shutdown, it’s ideal for advanced robotics, automation, and embedded projects demanding reliable, high-power motor management.

## Description

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). Features: Bidirectional control for one brushed DC motor Operating Voltage: DC 6V to 30V Maximum Motor Current: 20A continuous, 60A peak Buttons for quick testing LEDs for motor output state PWM and DIR inputs Inputs compatible with 1.8V, 3.3V, 5V and 12V logic (Arduino, Raspberry Pi, PLC, etc) PWM frequency up to 20kHz (Output frequency is same as input frequency) Compatible with sign-magnitude and locked-antiphase PWM operation Overcurrent protection with active current limiting Temperature protection Undervoltage shutdown Example Applications: Automated Guided Vehicle (AGV), Solar Tracker, Game Simulator, Mobile Robot, Automation Machine.

## Features

- 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
