  "textContent": "A drive apparatus includes a control chip, a watchdog chip, a drive logic circuit, and a plurality of drive chips. The control chip is connected to the watchdog chip and the drive logic circuit, and is configured to determine a PWM signal of each switch and output the PWM and a first signal to the drive logic circuit. The watchdog chip is connected to the drive logic circuit, and is configured to send a second signal. The first and the second pin of the drive chip are connected to the drive logic circuit. The third pin is configured to connect to a corresponding switch, and adjust a drive signal of the connected switch based on the received drive control signal and the received enable signal generated by the drive logic circuit.",
