MPL3115A2 Vddio/Vdd

[sebastienchrist]

Hi, on a portable application to save power and keep I2C bus working, is it possible to keep Vddio (4)  powered while Vdd (1) is not powered on MPL3115A2.

Thanks.

Hi,

When VDD is <1.8V, the device is powered off, all analog and digital blocks are shutdown and I2C bus inhibited.

If VDD is not present and VDDIO is present, the sensors would be in OFF mode and communications on the I2C interface are ignored. The I2C interface may be used for communications between other I2C devices and this sensor would not affect the rest of the I2C bus.

Have a great day,
Jose
