NORMAL mode is the highest performance mode of the device, in which the device is making regular measurements of voltage, current, and temperature, the LFO (low frequency oscillator) is operating, and the internal logic is powered for data processing and control. Full battery protections are operating, based on device configuration settings. Measurements of cell voltages, current, temperature, and other parameters are taken continuously, with timing determined by settings. If measurements are not required at the continuous rate, the Settings:Configuration:Power Config[LOOP_SLOW] parameter can be used to reduce the measurement rate and also reduce supply current.

The device is generally in NORMAL mode whenever any active charging or discharging is underway. When the current measurement falls below a programmable current threshold given by Power:Sleep:Sleep Current, the system is considered in relax mode, and the device can autonomously transition into SLEEP mode, depending on the configuration. The device includes a current wake detector, which triggers the device to exit SLEEP mode and return to NORMAL mode if a current in excess of a programmable threshold is detected.
