6.4 Device Functional Modes

To minimize power consumption, the fuel gauge has several power modes:

  • INITIALIZATION
  • NORMAL
  • SLEEP
  • and SHUTDOWN
The fuel gauge passes automatically between these modes, depending upon the occurrence of specific events, though a system processor can initiate some of these modes directly. For more details, see the BQ27427 Technical Reference Manual.
