MD04 - 24Volt 20Amp H Bridge Motor Drive

Devantech

Overview

The MD04 is a medium power motor driver, designed to supply power beyond that of any of the low power single chip H-Bridges that exist. Main features are ease of use and flexibility. The motor's power is controlled by Pulse Width Modulation (PWM) of the H-Bridge at a frequency of 15khz. Maximum voltage on the H-Bridge is 60v allowing Motor voltages up to 24vdc. Control of the module can be any of:

1. I2C bus, up to 8 MD04 modules at unique addresses.
2. 0v-2.5-5v analog input. 0v full reverse, 2.5v center stop, 5v full forward
3. 0v-5v analog input with separate direction control
4. RC mode. Controlled directly from the RC receiver output.
5. PWM. A simple on board filter means you can use a 0%-100% at frequencies above 20khz
6. Serial communication at TTL (5V) levels

Technical data

General usage and wiring considerations

The MD04 can handle high currents, and you will need to take a few precautions with wiring. It is very important that you do not allow motor current to flow in the logic ground path. Don't assume that just because the Battery, MD04 and Controller grounds are all together, that all is well. If at all possible, usetwo batteries, one for the logic and and the other for the motor power. Don't connect the battery grounds together, that is already done on the MD04. If you do, then you will only create a ground loop - and problems. The diagram below shows the general idea on keeping the logic and power sides electrically and physically separate from each other.
