咨询下：关于MC33978开关检测芯片。如果Battery 采用24V供电，SP0配置为检测高，SP0 输入5V能检测到吗？
If the Battery is powered by 24V and SP0 is configured to detect high. Can SP0 detect the input 5V is high level?
I do not fully understand your question, so let me answer in general.
The input is always compared with a 4V reference. When the pin is configured as a switch to battery, voltages greater than 4V are considered closed. Voltages less than 4V are considered open. On the other hand, when the pin is configured as a switch to ground, voltages greater than 4V are considered open, while voltages less than 4V are considered closed. Regardless of the setting, when the SPn input switch is closed a logic  will be placed in the status register.
I hope it answers your question.
Thanks Tomas, is sovled.
Got it, thanks.
