uniquegoods H-Bridge DC Dual Motor Driver PWM Module DC 3~36V 10A Peak 30A IRF3205 High Power Control Board for Arduino Robot Smart Car Application: Freescales Smart car, Undergraduate Electronic Design, A variety of DC motor control circuit The drive uses the full two half-bridge driver chip + low resistance N-channel MOSFET components. Complete 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. 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, 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. Dimensions: 4.25 x 2.16 x 0.71", net weight:2.01 oz
