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.

    本申请提供一种控制芯片、智能电子开关和汽车,该控制芯片包括电源供电引脚、电源接地引脚、使能引脚、驱动引脚、开启时间设置引脚、关断时间设置引脚和驱动电路,且开启时间设置引脚、关断时间设置引脚除了内接驱动电路外,开启时间设置引脚还用于外接第一电阻,关断时间设置引脚还用于外接第二电阻,第一电阻用于设置流过驱动引脚的开启电流,第二电阻用于设置流过驱动引脚的关断电流,第一电阻不同,对应的开启电流不同,第二电阻不同,对应的关断电流不同,使得功率开关的开启速度由开启电流确定,功率开关的关断速度由关断电流确定,实现了对功率开关的开启速度和关断速度的控制,保证了功率开关的开启速度和关断速度能够满足要求。
