Note 1:

A device’s supply current is mainly a function of the operating voltage and frequency, as well as tempera-

ture.

2:

The current measurements are as follows:

This is the peak active current value.

This value represents an average current measurement of active and low power mode time intervals during operation

measured over 1 second period.

This is the average idle current value when no sensor is actively providing environmental changes (and the device is

not in power-down mode).

This value is the current measured in power-down mode. This is the sleep state entered when the Host issues the

SET_POWER (Sleep) Command if the

Wakeup from power-down mode requires the HOST_TO_SH_WAKE pin if the
