VCOR
The VCOR bit enables the midrange voltage correction algorithm. When it is set, the bq2083V1P2 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
OTVC
The OTVC bit programs the bq2083V1P2 to perform a midrange voltage one time after a device reset.
0
One-time midrange correction disabled
1
One-time midrange correction enabled
Safety Control
Secondary Protection Limits for Li-Ion
The cell undervoltage (VUV) and overvoltage (VOV) limits are programmed in
Cell Under and Cell Over Voltage
DF 0x620x63, DF 0x600x61, respectively. Both value
s
are stored in mV.
Cell Over Voltage Reset
DF 0xef and
Cell Under Voltage Reset
0xd10xd2 set the reset points in mV for these safety parameters.
SAFE Threshold
The safety voltage threshold is programmed in
Safety Over Voltage
DF 0x680x69. It is stored in mV.
If Guage Configuration bit 2 (OVSEL) = 0 then Safety Over Voltage is based on pack voltage, but if OVSEL = 1,
then it is based on highest cell voltage.
The safety overtemperature (SOT) in
°
C is programmed in
Safety Over Temperature
DF 0x6a0x6b. It is stored
as
SOT
0.1
SafetyOvertemperature
AFE CONFIGURATION
The AFE protection limits are programmed as specified in the bq29311 data sheet.
AFE Brnout/Shutdn
0xb1 sets the brownout and shutdown voltage levels
AFE Over Curr Dsg
DF 0xb2 sets the overcurrent threshold on discharge.
AFE Over Curr Chg
DF 0xb3 sets the overcurrent threshold on charge.
AFE Over Curr Delay
DF 0xb4 sets the delay timing for over current in the charge and discharge direction.
AFE Short Circ Thresh
DF 0xb6 sets the short circuit threshold.
AFE Short Circuit Delay
DF 0xb7 sets the short circuit delay time.
AFE INTEGRITY CHECK
AFE Check time
DF 0xe4 sets the period in seconds for the AFE integrity check.
An
AFE Fail Limit
of 65,535 is the number of AFE integrity check failures that occur before the AFC flag is set.
SLEEP MODE
The sleep current threshold, SLP (mA), is stored in
Sleep Current Thresh
DF 0xe5 as:
SLP(mA)
0.5
Sleep Current Thresh
The wake-up period for current measurement, WAT(s), is set in
Sleep Current Time
DF 0xe6 as:
WAT(s)
0.5
Sleep Current Time
