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, obvious, easy to implement this feature uses the full two half-bridge driver chip + low resistance N-channel MOSFET components. Complete two half-bridge driver chip drive mode, the MOSFET switching losses to a minimum. 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 bootstrap capacitor, so that the tube has enough drive voltage of the MOSFET channel can be opened quickly, motor acceleration curvature, also quickly for the motor brake. This allows the trolley can quickly can quickly kill the car. The driver can operate at 0% -99% of the duty of the PWM modulation, the motor driving voltage can be obtained sufficiently. Motor forward: DIR = 1 PWM = PWM Motor reversal: DIR = 0 PWM = PWM Parking brake: DIR = X PWM = 0 (X is an arbitrary state) Motor and POWER connected to the positive power supply, GND power supply is negative. Two motors were connected MOTOR1, MOTOR2 Parameter: Rated voltage: 3v-36v Rated Current: 15A current: 30A Use: Freescale smart car contest Undergraduate Electronic Design Contest of DC motor control circuit Dimensions: length 108mm, width 58mm Model Number: DC Motor Driver color:Green :plastic Package Contents: 1 x DC motor drive board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
