The device can be operated in either active or sleep states. The Sleep state is complete shutdown, but the active state can have a variety of
different current consumptions depending on the settings. Some examples are given here: The Sleep state is the default state after
power-on-reset. The chip can then be placed into an active state after a valid I2C communication is received.
