ir2104 driver

1: Product Introduction
This product uses 6V~16V power supply and is suitable for battery application scenarios.
Two: The application scenario
meets the 2S~3S power supply requirements, and can be perfectly installed on the rear of the smart car C/D/F car model. Small in size and efficient in performance, it meets the learning needs in the early preparation process of the competition.
Three: Product Overview
How to use: This product is a pure hardware product and can be used after powering on. Change the operating status of the motor by changing the input of the 4 PWM signal lines. For example: A1 terminal is given a certain duty cycle, and the A2 terminal duty cycle is 0, the motor output port A rotates forward; B2 terminal is given a certain duty cycle, and the B1 terminal duty cycle is 0, the motor output port B rotates reversely. There are also power input buttons and hardware enable buttons. You can judge whether the driver board is working through the LED under the button.
Product features: Double protection for signal and power supply. A digital isolation chip π140U30 is placed at the signal input end to protect the input end (MCU). A large capacitor and TVS tube are connected in parallel at the power input end to absorb surges and buffer the power supply end.
Performance is efficient. The signal pin of the driver chip is connected in reverse parallel with the diode to speed up the MOS turn-off rate to reduce the influence of the parasitic capacitance of the MOS tube.
