SLUSE14B December 2020 – December 2021 BQ76942
NORMAL mode is the highest performance mode of the device, in which the device regularly measures 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 operate based on device configuration settings. System current is measured at intervals of 3 ms, with cell voltages measured at intervals of 45 ms or slower, depending on configuration. The device also provides a configuration bit that causes the conversion speed for both voltages and CC2 current to be doubled, with a reduction in measurement resolution.
The device is generally in NORMAL mode when any active charging or discharging is underway. When the CC1 Current() measurement falls below a programmable current threshold, the system is considered in relax mode, and the BQ76942 device can autonomously transition into SLEEP mode, depending on configuration.
