LSM6DSO32 taking High Current

[V.Jose]

I have powered from LSM6DSO32 through a 3V Coin cell battery and connected with Nrf52810 using I2C.

Without any coding sensor taking around 2mA and after flashing its taking 4MA.

I am getting the readings correctly.

Attached the schematics

Hi @V.Jose​ ,

the baseline consumption looks high too... did you placed pull-up resistors on I2C lines?

Note that, as reported in the datasheet, both I2C lines (SDA and SCL) the lines must be connected to Vdd_IO through external pull-up resistors. When the bus is free, both the lines are high, so if you tie them to GND by default in your application processor, you might experience high current consumption.

Hi, Eleon,

Thanks for your response. we are using internal pullup

Hi @V.Jose​ ,

are the pullups always active, even when you do not communicate I2C?
