9-24V 7A Dual DC Motor Driver Module 160W PWM H-bridge

9-24V 7A Dual DC Motor Driver Module 160W PWM H-bridge is a motor driver capable of driving two or more high-powered brushed DC motors.  This motor driver comes with pluggable connectors for motor and power, making installation and swapping drivers easy. The motor driver uses PWM signals to control the speed direction of the motors and therefore is able to be easily integrated and used with most microcontrollers.

This motor driver can be used to drive the high-performance DC motors or driving small to medium-sized robots.

Features:

• Double H bridge, which can drive two DC motors with single 7A current, high power;
• Wide voltage input 6.5V ~ 27V;
• Signal optocoupler isolation input, IO port can be directly controlled, without interference;
• Under voltage protection, to prevent instantaneous high-current burned module;
• High-power TVS and electrostatic discharge circuit, inhibit the transient interference pulse and static, enhanced EMC performance, stable and reliable product, industrial design.

Control Signal Logic:

IN1	IN2	ENA/ ENB	Motor1/2 Behavior
0 (LOW)	0 (LOW)	x (Floating)	Stop (brake)
1 (HIGH)	1 (HIGH)	x (Floating)	Motor shaft free spin
1 (HIGH)	0 (LOW)	1 (HIGH)	Forward 100%
0 (LOW)	1 (HIGH)	1 (HIGH)	Reverse 100%
1 (HIGH)	0 (LOW)	PWM (0-255)	Forward at PWM speed
0 (LOW)	1 (HIGH)	PWM (0-255)	Reverse at PWM speed

Precautions:

• Drive power must not be reversed, the proposed power connector in series 15A fuse, the voltage should be between 6.5 ~ 27V. If the voltage is over-voltage, power-on may burn the drive module.
• It is recommended that the rated output current of the power supply should be at least 2 times of the rated current of the motor so that the power supply can not supply the required voltage when the motor starts.  Off the output lead to the phenomenon of motor pause.
• Do not short-circuit the motor interface, or may burn the driver module, the proposed electrical interface in series 10A fuse.
• In the forward and reverse switch when the need to brake 0.1S above and then reverse, not in the motor has not stopped when the commutation, or it may damage the drive.
• Drive module power-down, do not directly or indirectly, high-speed rotation of the motor, or motor  generated electromotive force may burn the drive module.
• If the application requires a high-speed rotation of the motor when the drive module is powered down, it is     recommended that the motor interface of the driver is connected in series with a relay (NO and COM             terminals), and the relay coil and the driver are connected in common. In this way, when the power down, the relay will disconnect the drive and the motor connection.
