8.5.1.1.7 BAT_REMOVE: 0X000D

This subcommand forces the Flags() [BAT_DET] bit to clear when the battery insertion detection is disabled

through Op Config [BIE] = 0. In this case, the gauge does not detect battery removal from the BIN pin logic

state, but relies on the BAT_REMOVE host subcommand to indicate battery removal from the system.

8.5.1.1.8 SET_HIBERNATE: 0x0011

Instructs the fuel gauge to force the CONTROL_STATUS [HIBERNATE] bit to 1. If the necessary conditions are

met, this enables 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.

8.5.1.1.9 CLEAR_HIBERNATE: 0x0012

Instructs the fuel 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.

8.5.1.1.10 SET_CFGUPDATE: 0x0013

Instructs the fuel gauge to set the Flags() [CFGUPMODE] bit to 1 and enter CONFIG UPDATE mode. This

command is only available when the fuel gauge is UNSEALED.

NOTE

A SOFT_RESET subcommand is typically used to exit CONFIG UPDATE mode to resume

normal gauging.

8.5.1.1.11 SEALED: 0x0020

Instructs the fuel gauge to transition from UNSEALED state to SEALED state. The fuel gauge should always be

set to SEALED state for use in end equipment.

8.5.1.1.12 RESET: 0x0041

This command instructs the fuel gauge to perform a full device reset and reinitialize RAM data to the default

values from ROM. The gauge sets the Flags() [ITPOR] bit and enters the INITIALIZE mode. See Figure 6. This

command is only available when the fuel gauge is UNSEALED.

8.5.1.1.13 SOFT_RESET: 0x0042

This command instructs the fuel gauge to perform a partial (soft) reset from any mode with an OCV

measurement. The Flags() [ITPOR, CFGUPMODE] bits are cleared and a resimulation occurs to update

StateOfCharge( ). See Figure 6. This command is only available when the fuel gauge is UNSEALED.
