This device supports five modes, but the current consumption varies, based on firmware control of certain functions and modes of operation:

• NORMAL mode: In this mode, the device performs measurements, calculations, protections, and data updates every 250-ms intervals. Between these intervals, the device operates in a reduced power state to minimize total average current consumption. Battery protections are continuously monitored and both protection NFETs are typically on.
• SLEEP mode: In this mode, the device performs measurements, calculations, and data updates in adjustable time intervals. Between these intervals, the device operates in a reduced power stage to minimize total average current consumption. Battery protections are continuously monitored and both protection NFETs are typically on.
• SHIP mode: In this mode, the device measures voltage and temperature very infrequently and at shorter ADC conversion times, and current is not measured or coulomb counted. Current is assumed to be, and reported as, 0 mA. Therefore, the device tracks the battery's state-of-charge from OCVs. The measurements performed each interval arecell voltage, temperature, and PACK voltage (every fourth interval). Processing is minimized by reducing the number of calculations. Some calculations are performed less frequently: only after voltage and temperature are measured. These less frequent calculations include updating firmware-based protections, lifetime data, and the voltage and temperature ranges of the advanced charge algorithm. Other calculations, such as updating RemainingCapacity() and FullChargeCapacity(), are not performed at all with the assumption the system is off and will not communicate with the gauge. Battery protections are continuously monitored and both protection NFETs remain on, typically.
• SHELF mode: In this mode, power consumption is reduced even further from SHIP mode by turning off the CHG and DSG NFETs and all hardware-based protections. Due to this, no external power is available to the system in SHELF mode. The device measures voltage and temperature very infrequently and at shorter ADC conversion times, and current is not measured or coulomb counted. Current is assumed to be, and reported as, 0 mA. Therefore, the device tracks the battery's state-of-charge from voltage measurements. The measurements performed each interval arecell voltage, temperature and PACK voltage (every fourth interval). Processing is minimized by reducing the number of calculations. Some calculations are performed less frequently: only after voltage and temperature are measured. These less frequent calculations include updating firmware-based protections, lifetime data, and the voltage and temperature ranges of the advanced charge algorithm. Other calculations, such as updating RemainingCapacity() and FullChargeCapacity(), are not performed at all with the assumption the system is off and will not communicate with the gauge.
• SHUTDOWN mode: In this mode, the device is completely disabled to minimize power consumption and to avoid depleting the battery.
