Description:

Parking brake: DIR = X PWM = 0 (X is an arbitrary state)

Motor forward: DIR = 1 PWM = PWM

The drive performance of these non-L298 motor driver chip can be compared.

The driver focus on current and efficiency, effectively motor power and battery life.

Can withstand high current overload, the maximum current up to 30A

This drive also has a brake function can be quickly stopped the motor, brake quickly, braking obvious, easy to implement this feature

The drive uses the full two half-bridge driver chip + low resistance N-channel MOSFET components.

Completer two half-bridge driver chip reliable drive mode, the MOSFET switching losses to a minimum. Improve power utilization.

MOSFET driver chip comes with hardware brake function and power feedback.

This drive is superior integrated low power chip solution and the other half-bridge power margin in the coordinated combination of programs and complex issues and complementary drive problems

N-channel MOSFET IRF3205 MOSFET, use two dedicated half-bridge driver chip on the top tube using the boostrap capacitor, so that the tube has enough drive voltage of the MOSFET channel can be opened quickly, improve motor acceleration curvature, but also quickly for the motor brake. This allows the trolley can quickly start can quickly kill the car.

The driver can operate at 0-99% of the duty cycle of the PWM modulation, the motor driving voltage can be obtained sufficiently.

Motor reversal: DIR = 0 PWM = PWM

POWER connected to the positive power supply, GND power supply is negative. Two motors were connected MOTOR1, MOTOR2
