SET_HIBERNATE: 0x0011
Instructs the fuel 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.
CLEAR_HIBERNATE: 0x0012
Instructs the fuel gauge to force the CONTROL_STATUS[HIBERNATE] and [HIBE] 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.
SET_CFGUPDATE: 0x0013
Instructs the fuel gauge to set the CONTROL_STATUS[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 for use resume normal gauging.
FACTORY_RESTORE: 0X0015
Instructs the fuel gauge to reset learned resistance tables and Qmax values (default = DesignCapacity) to the
default values. This command is only available when the fuel gauge is UNSEALED.
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.
RESET : 0x0041
This command instructs the fuel gauge to perform a full device reset and reset RAM data to the default values
from ROM. This command is only available when the fuel gauge is UNSEALED.
SOFT_RESET : 0x0042
This command instructs the fuel gauge to perform a partial reset to reinitialize configuration data and clear the
ITPOR bit of the Flags( ) register to resume normal gauging from CONFIG UPDATE mode. This command is
only available when the fuel gauge is UNSEALED.
