<p>Application: For Freescale's Smart car, Undergraduate Electronic Design, A variety of DC motor control circuit; uses the full two half-bridge driver chip + low resistance N-channel MOSFET components. </p> <p>Complete two half-bridge driver chip reliable drive mode, the MOSFET switching losses to a minimum. Improve power utilization. </p> <p>MOSFET driver chip comes with hardware brake function and power feedback.</p> <p>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. </p> <p>This allows the trolley can quickly start can quickly kill the car.</p> <p>The driver can operate at 0% -99% of the duty cycle of the PWM modulation, the motor driving voltage can be obtained sufficiently.</p> <p>Material:Plastic + Metal</p> <p>Colour:Green</p> <p>Dimensions: 100 x 70 x 21mm</p> <p>net weight:2.01 oz</p> <p>Motor being transferred: DIR = 1 PWM = PWM </p> <p>Motor Reverse: DIR = 0 PWM = PWM </p> <p>Parking brake: DIR = X PWM = 0 (X is an arbitrary state) </p> <p>Motor and : POWER connected to the positive power supply, GND power supply is negative. </p> <p>Two motors were connected MOTOR1, MOTOR2 </p> <p>Rated voltage: DC 3V~36V </p> <p>Rated current: 15A </p> <p> Current: 30A </p> <p>Package Included: 1 x H-Bridge DC Motor Driver</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
