7.6.6.4.1 SET_FULLSLEEP: 0X0010
Instructs the gas gauge to set the FULLSLEEP bit in the Control Status register to 1. This allows the gauge to
enter the FULLSLEEP power mode after the transition to SLEEP power state is detected. In FULLSLEEP mode,
less power is consumed by disabling an oscillator circuit used by the communication engines. A communication
to the device in FULLSLEEP forces it back to SLEEP mode.
7.6.6.4.2 SET_HIBERNATE: 0x0011
Instructs the gas gauge to force the CONTROL_STATUS [HIBERNATE] bit to 1. This allows the gauge to enter
the HIBERNATE power mode after the transition to SLEEP power state is detected. The [HIBERNATE] bit is
automatically cleared upon exiting from HIBERNATE mode.
7.6.6.4.3 CLEAR_HIBERNATE: 0x0012
Instructs the gas gauge to force the CONTROL_STATUS [HIBERNATE] bit to 0. This prevents the gauge from
entering the HIBERNATE power mode after the transition to SLEEP power state is detected. It can also be used
to force the gauge out of HIBERNATE mode.
7.6.6.4.4 SET_SHUTDOWN: 0x0013
Sets the CONTROL_STATUS [SHUTDOWN] bit to 1, enabling the device to enter SHUTDOWN mode if the
appropriate conditions are met.
7.6.6.4.5 CLEAR_SHUTDOWN: 0X0014
Clears the CONTROL_STATUS [SHUTDOWN] bit to 1, disabling the device from entering SHUTDOWN mode.
7.6.6.4.6 DSG FET OFF (HOST_DISCONNECT): 0x0017
Instructs the gas gauge to force the protection DOUT pin to low level. This prohibits discharging the battery by
turning off the external discharge control N-channel MOSFET.
7.6.6.4.7 DSG FET ON (HOST_CONNECT): 0x0018
Instructs the gas gauge to force the protection DOUT pin to high level. This allows discharging the battery by
turning on the external discharge control N-channel MOSFET.
