50a driver motor shield for arduino high current for strong sumo robot

Detail 50a driver motor shield for arduino high current for strong sumo robot

escription :

This motor driver works with single channel max 50A load capacity. This module performs far better than MC33886 or L298 motor driver, especially in terms of motor speed control and power efficiency.

This drive has a brake function, which can quickly stop the motor. And the operation is very easy.The drive module contains a full-bridge driver chip and MOSFET with low internal resistance. The full-bridge driver IC minimizes the switching loss of MOSFET and improves power efficiency.

MOSFET is current impact-resistant type, with internal resistance of 0.003 Ohm. MOSFET channel can be opened quickly to improve the motor's speed curvature, and also brake the motor quickly. This function can make the car start or stop quickly.

This driver module can work under the PWM duty cycle of 0% -98%.

Electronic Parameter :

1Peak current (Load): 50A

2Recommend max working current(Load): 20A

3Power VCC (Load): 0V~30V

4Recommend power vcc(load) : 12V ~ 26V

5Control VCC: 4V~12V

6Control TTL Voltage; 2.5V ~ 12V

Notice :

1) : Control TTL voltage means the High voltage of the control pins (EN, LPWM, RPWM, DIS).

2) : The stable max working current is 20A while load vcc is between 12V~30V. The current is restricted by heat dissipation. Current, we don't add any heat radiator on the board•So if the current is over 20A, the heat may melt the sldering tin and cause problems. If you want it working stable at higher current, you should add radiator.

3) : Power VCC is recommended to be higher than 12V if your load is large-current devices. While over 12V, the MOSFET is working fully and its power consumption is small. So the heat will be less. If your load current is not large and just several Amperes, the power VCC can be as low as 3V.
