OPERATION
be set to indicate calibration in progress. Soft-start ramps
the discharge current at a rate set by the capacitor on the
ITH pin (typically 10ms with 0.1μF capacitor). A limit to
how far the battery cell voltage will be discharged during
calibration can be programmed with the VCAL pin (Li-Ion
default = 2.75V/cell, lead acid default = 1.93V/cell, Smart
NiMH/NiCd default = 0.95V/cell). When the limit is reached
calibration is terminated, the CAL_COMPLETE bit in the
BBuStatus() register is set, the CAL_ON bit in the BBuS-
tatus() register will be cleared and the charge mode is
automatically entered to begin recharging the battery. If
the GPIO3 is congured as a calibration complete status
output (CAL_COMPLETEb), it will be forced low until reset
by the CAL_RESET write bit. Calibration is inhibited during
backup or shutdown modes. Calibration is also inhibited
when a thermistor is sensed absent.
During calibration, user-programmable supply back-drive
protections are provided. These protections prevent a
reversal of current into the main supply and/or possibly
raising the supply voltage to unsafe levels should the
