Description Application: For Freescales Smart car, Undergraduate Electronic Design, A of DC motor control circuit; 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. 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. Material:Plastic + Metal Colour:Green Dimensions: 100 x 70 x 21mm net weight:2.01 Motor being transferred: DIR = 1 PWM = PWM Motor Reverse: DIR = 0 PWM = PWM Parking brake: DIR = X PWM = 0 (X is an arbitrary state) Motor and : POWER connected to the power supply, GND power supply is negative. Two motors were connected MOTOR1, MOTOR2 Rated voltage: DC 3V~36V Rated current: 15A Current: 30A Package Included: 1 x H-Bridge DC Motor Driver Only the above package content, other are not included.
