The drive performance non-L298 these motor-driven chips can be compared, the drive focus on current and efficiency, effectively play the motor power and battery life. Can withstand high current overload, the maximum current up to 30A.
This drive also has a brake function that can quickly stop the motor, brake quickly, brake is clear, to achieve this function is simple.
The driver uses a complete two-chip half-bridge driver chip + very low resistance of the N-channel MOSFET composition. The complete two-chip half-bridge driver chip reliable drive, so that MOSFET switching losses to a minimum. Improve power utilization. MOSFET driver chip comes with hardware brakes and power feedback.
This driver is superior to the integrated power chip scheme with low power margin and other half-bridge combination schemes in terms of timing complex problems and complementary driving problems.
MOSFET using N-channel IRF3205 MOSFET, the use of two dedicated half-bridge driver chip, the upper tube with bootstrap capacitor, so that the tube has enough drive voltage, can quickly open the MOSFET channel to improve the motor speed of curvature, but also Can quickly brake for the motor. This can make the car can quickly start also quickly kill the car.
The drive can operate from 0% to 99% of the PWM modulation duty cycle so that the motor can get enough drive voltage.
control signal:
Motor forward: DIR = 1 PWM = PWM
Motor reverse: DIR = 0 PWM = PWM
Parking brake: DIR = X PWM = 0 (X is any state)
The motor is connected to the power supply
POWER to the positive side of the power supply, GND connected to the power supply negative. Two motor respectively MOTOR1, MOTOR2
