PROGRAMMING INFORMATION
pack options (continued)
VCOR
The VCOR bit enables the midrange voltage correction algorithm. When it is set, the bq2063 compares the pack
voltage to RM and may adjust RM according to the values programmed in VOC25, VOC50, and VOC75.
0 Continuous midrange corrections disabled
1 Continuous midrange corrections enabled
EXTH
The EXTH bit configures the bq2063 for external or internal temperature measurement. When this bit is set, the
bq2063 expects an external thermistor input on the TS pin. When the bit is not set, the bq2063 uses its internal
temperature sensor.
0 Internal temperature sensor used
1 External thermistor used
OTVC
The OTVC bit programs the bq2063 to perform a midrange voltage one time after a device reset.
0 One-time midrange correction disabled
1 One-time midrange correction enabled
4CELL
The 4CELL bit programs the bq2063 for three or four series-cell operation.
0 Configure the bq2063 for three cells
1 Configure the bq2063 for four cells

CVUV or CVOV sets immediately on first fault measurement
CVUV or CVOV requires two successive VOC measurements (2-second intervals).
EDVV
The EDVV bit selects whether EDV the termination is to be done with regard to voltage or the lowest single-cell
voltage.
0 EDV conditions determined on the basis of the lowest single-cell voltage
1 EDV conditions determined on the basis of Voltage( ).
LLRN
LLRN bit sets the threshold above which current must be when RM reaches the Low Battery % or when
Voltage( ) reached the EDV2 to level to maintain a qualified discharge and allow learning (FCC update).
0 Sets the threshold to 3C/32
1 Sets the threshold to C/32
