Abstract: A drive apparatus and an electric vehicle with a vehicle regulation drive chip are disclosed. The 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 pulse width modulation PWM signal of each switch, output the PWM and a first signalto 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, whenthe 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 that generated by the drive logic circuit.

Abstract: This application provides a power supply system for a motor control module and a vehicle. The power supply system includes a first current limiting unit and an isolation unit. An output end of a first direct current power supply is coupled to a first input end of the isolation unit to form a first power supply loop with the isolation unit. A first output end of a second direct current power supply is coupled to one end of the first current limiting unit. Another end of the first current limiting unit is coupled to a second input end of the isolation unit to form a second power supply loop with the isolation unit. The second power supply loop is connected in parallel to the first power supply loop.
