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 Motor and Use: Freescale smart car contest Undergraduate Electronic Design Contest variety of DC motor control circuit Rated Current: 10A current: 30A Material: PC+Metal colour: As shown Package Contents: 1 x Dual DC Motor Driver Board H-Bridge Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
