The invention provides a control chip, an intelligent electronic switch and an automobile, the control chip comprises a power supply pin, a power supply grounding pin, an enabling pin, a driving pin, a turn-on time setting pin, a turn-off time setting pin and a driving circuit, and the turn-on time setting pin and the turn-off time setting pin are internally connected with the driving circuit and also internally connected with the driving circuit. The turn-on time setting pin is further used for being externally connected with a first resistor, the turn-off time setting pin is further used for being externally connected with a second resistor, the first resistor is used for setting turn-on current flowing through the driving pin, the second resistor is used for setting turn-off current flowing through the driving pin, and different first resistors correspond to different turn-on current and different second resistors. According to the invention, the corresponding turn-off currents are different, so that the turn-on speed of the power switch is determined by the turn-on current, and the turn-off speed of the power switch is determined by the turn-off current, thereby achieving the control of the turn-on speed and the turn-off speed of the power switch, and guaranteeing that the turn-on speed and the turn-off speed of the power switch can meet the requirements.
