Where CHM is:
0
Selects Nickel
1
Selects Li-Ion
Bit 4, the
Charge Control
flag (CC), determines whether
a bq2092-based charge termination will set RM to a
user-defined programmable full charge capacity.
The CC values are:
Where CC is:
0
RM is not modified on valid bq2092
charge termination
1
RM is set to a programmable percentage of
the FCC when a valid bq2092 charge termi-
nation occurs
Bit 3 is reserved.
Bit 2, the
Overvoltage
flag (OV), is set when the bq2092
detects a pack voltage 5% greater than the programmed
charging voltage. This bit is cleared when the pack volt-
age falls 5% below the programmed charging voltage.
The OV values are:
Where OV is:
0
BatteryVoltage() < 1.05
ChargingVoltage
1
BatteryVoltage()
≥
1.05
ChargingVoltage
Bit 1, the
Low Temperature Fault
flag (LTF), is set when
temperature < 0°C and cleared when temperature > 5°C.
The LTF values are:
Where LTF is:
0
Temperature > 5°C
1
Temperature < 0°C
Bit 0, the
Overcurrent
flag (OC), is set when the average
current is 25% greater than the programmed charging
current. If the charging current is programmed less than
1024mA, overcurrent is set if the average current is
256mA greater than the programmed charging current.
This flag is cleared when the average current falls below
256mA.
The OC values are:
Where OC is:
0
Average current is less than 1.25
charg-
ing current or less than 256mA if charging
current is programmed less than 1024mA
1
Average current exceeds 1.25
charging
current or 256mA if the charging current is
programmed less than 1024mA. This bit is
cleared if average current < 256mA
FLAGS1
Bits 7 and 6 are reserved. The
Valid Charge
flag (VQ),
bit 5, is set when V
SRO
≥
|V
SRD
| and 10mAh of charge
has accumulated. This bit is cleared during a discharge
and when V
SRO
≤
|V
SRD
|.
The VQ values are:
Where VQ is:
0
V
SRO
≤
|VSRD
|
1
V
SRO
≥
|V
SRD
| and 10mAh of charge has
accumulated
The
Write Inhibit
flag (WRINH), bit 4, allows or inhibits
writes to all registers.
The WRINH values are:
Where WRINH is:
0
Allows writes to all registers
1
Inhibits all writes and secures the bq2092
from invalid/undesired writes.
