Why is LSM6DSL using so much current in power-down?

We are seeing a large current draw when the LSM6DSL is in power-down mode, or low-power mode. The current measured is roughly 120 uA. IC is wired for I2C. We have an identical setup with a LIS3DH that does not have this issue.

 

Is there a register we need to change? Again , this 120 uA appears when power is supplied to the IC.

 

LSM6DSL Connections:

 

SDO: Unconnected

SA0:  Unconnected

SDx: Connected to Ground

SCx: Connected to Ground

INT1: Floating

INT2: Floating

CS: External pull-up with 10k

SCL: Connected to MCU i2c lines and other I2C devices - External pull-up with 10k

SDA: Connected to MCU i2c lines and other I2C devices - External pull-up with 10k
