SLUSAS4A – OCTOBER 2012 – REVISED SEPTEMBER 2014

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.
