NORMAL mode is the highest performance mode of the device, in which the device is making regular measurement of voltage, current, and temperature, the LFO (low frequency oscillator) is operating, and the internal processor powers up (as needed) for data processing and control. Full battery protections are operating, based on device configuration settings. System current is measured at intervals of 3ms, with cell voltages measured at intervals of 63ms or slower, depending on configuration. If the [FASTADC] configuration bit is set, the conversion speed for both voltages and currents is doubled, with a reduction in measurement resolution.

The device will generally be in NORMAL mode whenever any active charging or discharging is underway. When the CC1 Current measurement falls below a SLEEP current threshold given by Power:Sleep:Sleep Current, the system is considered in relax mode, and the BQ76922 device can autonomously transition into SLEEP mode, depending on the configuration.
