Improve power utilizationthis driver pays attention to current and efficiency, and effectively exerts motor power and battery lifecan withstand large current overload, the maximum current can reach 30athe mosfet driver chip has its own hardware braking function and power feedback functionthe driver is superior to the complex problem of timing coordination and complementary driving problems in the integrated power chip solution with low power margin and other half-bridge combination solutionthis can make the car can start quickly and kill the car quicklythe mosfet adopts n-channel irf3205 mosfet, uses two dedicated half-bridge driver chips, and uses a bootstrap capacitor for the upper tube, so that the upper tube has enough driving voltage, which can quickly turn on the mosfet channel and improve the acceleration curvature of the motorthis driver also has a braking function that can quickly brake the motor, the braking is rapid, the braking is obvious, and the operation is simple to achieve this functionfeature:the performance of this driver is not comparable to those of l298 motor driver chipsthe reliable driving method of the complete two-piece half-bridge driver chip minimizes the switching loss of the mosfetit can quickly brake the motorthe driver is composed of two complete half-bridge driver chips + extremely low internal resistance n-channel mosfetthe driver can work at 0%-99% pwm modulation duty cycle, so that the motor can get enough driving voltage
