    BHI360 max. voltage on I2C-bus

    BHI360 max. voltage on I2C-bus

    Hello,

    max. voltage of VDD and VDDIO is clear.

    But the data sheet does not say anything about a max. voltage for IO-input:

    18.3 Electrical Characteristic Table
    Voltage Input High Level VIH: "Max" is empty.

    My understanding is that BHI360 can be connected to 3.3V-I2C-bus.

    Please confirm.

    Hi MartinBcn,

    I2C bus is a part of the VDDIO domain, with a typical supply voltage of 1.8V. It cannot accept 3.3V power supply.
