Welcome to the store! Usage: For Freescale's Smart car, Electronic design for students, A of DC motor control circuit; uses the full two half-bridge driver chip + low resistance N-channel MOSFET components. Full two half-bridge driver chip reliable drive mode, MOSFET switching losses to a minimum. Improve power utilization. MOSFET driver chip comes with hardware brake function and power feedback. N-channel MOSFET IRF3205 MOSFET, use two dedicated half-bridge driver chips on the upper tube using the bootstrap capacitor, so that the tube has sufficient drive voltage for the MOSFET channel to open quickly, improve the motor's acceleration curve, but also quickly for motor braking. This allows the car to start quickly and kill the car quickly. The driver can work at 0% -99% of the duty cycle of PWM modulation, the motor drive voltage can be obtained sufficiently. Material: Plastic + Metal Color: Green Dimensions: 100 x 70 x 21 mm Net weight: 2.01 oz Motor Forward: DIR = 1 PWM = PWM Motor Reverse: DIR = 0 PWM = PWM Parking Brake: DIR = X PWM = 0 (X is an arbitrary state) Motor Power: POWER connected to the positive 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 products are not included.
