24V 20A H Bridge Motor Drive

The MD03 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 on-board Pulse Width Modulation (PWM) generators driving the H-Bridge Transistors.

• Voltage - 5v logic supply and 5v - 24v for the motor
• Current - 50mA Max for logic and up to 20A for the motor
• Control 1 - 0v - 2.5v - 5v Analogue for Reverse - Stop - Forward
• Control 2 - 0v - 5v (or PWM equiv.) with separate direction control
• Control 3 - RC Mode - Controlled by standard Radio Control system. Direct connection to RC receiver. (1mS - 2mS pulse with 1.5mS center off).
• Control 4 - I2C Interface, full control, acceleration and status reporting. Up to 8 modules on bus. SCL speed up to 1MHz
• Current limiter - Preset at 20A
• Temperature limiter - Reduces power gracefully if module overheats
• Size - 113mm x 52mm x 30mm
