1Motor control function, which is small and lightweight, can be used to control ordinary DC motors, smart car motors, etc., and can help you better use and adjust. 2Reversible control and PWM speed control. Its PWM duty cycle is 098%. In terms of PWM frequency, the generalpurpose motor is 16kHz, the coreless motor is 80kHz, and the TEC is 500Hz80 kHz. 3Composed of a complete MOSFET, it has extremely low internal resistance. Builtin reliable drive mode minimizes the switching loss of MOSFET and improves power utilization. 4Multifunctional design, MOSFET driver chip has its own hardware braking function and power feedback function, which can have strong practicability and driving ability. 5Highspeed switch design, it has ultralow internal resistance, low heat generation, working voltage is DC 512V, each channel working current is 0A30A (maximum), peak current is 70A (maximum).
