LIS2DW12中断引脚如何在内部连接?

LIS2DW12,如果中断引脚(INT1和INT2)配置为开漏模式,如果VDDIO电源被截止,它们是否仍然有效? (并且中断引脚被上拉到另一个电源电压)并且VDD仍然连接到1.8V? VDD电压是否仍然可以控制开漏引脚,还是由VDDIO电压完全馈电?

LIS2DW12, if interrupt pins (INT1 & INT2) are configured to open-drain mode, will they still work if the VDDIO supply is cutoff? (and the interrupt pins are pulled up to another supply voltage) and the VDD is still connected to 1,8V ? Will the VDD voltage still control the open-drain pins or is it completely fed by the VDDIO voltage?

在我们的应用中,我们希望LIS2DW12始终处于某种低功耗模式。我认为我们仍然会在VDDIO端出现一些泄漏。但内部上拉是我们不使用的引脚。
感谢您及时的回复。我的问题得到了回答。

In our application, we would like to leave the LIS2DW12 always on in some lowpower mode. I thought we still would have some leakage on the VDDIO side of things. But the internal pull-ups are on pins we don't use.
Thanks for the quick response. My question is answered.
