Building a RC vehicle or mobile robot without any microcontroller? MDDRC10 is what you need. It’s plug and play and can be connected directly to the RC receiver. No coding or programming is needed. Selectable mixed mode allow the differential drive motors to be controlled from a throttle (forward-reverse) and a steering channel. Onboard switching regulator which produces 5V output is also available to power the RC receiver. This eliminates the need of extra battery eliminator circuit (BEC).
MDDRC10 is able to drive two brushed DC motors from 7V to 30V. With discrete NMOS H-Bridge design, this motor driver is able to support 10 Amp per channel continuously without any additional heatsink.
The onboard test buttons and motor output LEDs allow functional test of the motor driver in a quick and convenient way.
Various protection features are also incorporated in the MDDRC10. Overcurrent protection prevents the motor driver from damage when the motor stalls or an oversized motor is hooked up. When the motor is trying to draw current more than what the motor driver can support, the motor current will be limited at the maximum threshold.
Assisted by temperature protection, the maximum current limiting threshold is determined by the board temperature. The higher the board temperature, the lower the current limiting threshold. This way, MDDRC10 is able to deliver its full potential depending on the actual condition without damaging the MOSFETs.
Note: Power input does not have reverse-voltage protection. Connecting the battery in reverse polarity will damage the motor driver instantaneously.
