SLEEP mode performs AverageCurrent(), Voltage(), and Temperature() less frequently which results in reduced power consumption. SLEEP mode is entered automatically if the feature is enabled (Pack Configuration [SLEEP] = 1) and AverageCurrent() is below the programmable level Sleep Current. Once entry into SLEEP mode has been qualified, but prior to entering it, the fuel gauge performs an ADC autocalibration to minimize offset.
During the SLEEP mode, the fuel gauge periodically takes data measurements and updates its data set. However, a majority of its time is spent in an idle condition.
The fuel gauge exits SLEEP if any entry condition is broken, specifically when either:
