Features: 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. 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 problemsN-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.ParameterMotor forward: DIR = 1 PWM = PWMMotor reversal: DIR = 0 PWM = PWMParking 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, MOTOR2Rated voltage: 3v-36v (can be customized according to the )Rated Current: 10A current: 30AUse: Freescale smart car contest Undergraduate Electronic Design Contest of DC motor control circuitDimensions: length 108mm x 58mm widthMaterial: pcbcolour: GreenPackage Contents:1 x Dual Motor DriverOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
