Question for LPS25HB Pin#7 connection

genki · ‎2024-06-10

I am designing to mount LPS25HB on the board.

Communication is I2C.

Please help me with the connection of Pin 7 (INT_DRDY).
Is this pin an open pad? Or does it need to be connected to GND?

Hi @genki ,

Welcome to ST Community!

INT_DRDY pin is an output of the device. If not used can be left floating. In other case it must be connected to GPIO of microcontroller to verify the features of this pin (see page 37 of LPS25HB datasheet)
