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 in 250-ms intervals. Between these
intervals, the device is operating in a reduced
power stage to minimize total average current
consumption.
- SLEEP mode: In this mode, the device performs
measurements, calculations, and data updates in
adjustable time intervals. Between these
intervals, the device is operating in a reduced
power stage to minimize total average current
consumption.
- DEEP SLEEP mode: In this mode,
the current is reduced slightly while current and
voltage are still measured periodically, with a
user-defined time between reads.
- HIBERNATE mode: In this mode,
the device is completely disabled with CE
remaining high. This mode is exited upon two valid
communications within a specified time
window.
- OFF mode: The device is completely disabled by
pulling CE low. CE disables the internal voltage
rail. All nonvolatile memory is unprotected.
