When Miscellaneous Configuration (0x2a) bit 5 AC is set, and the AFE has failed at least AFE Fail Times (DF
0xd3, d4)
The bq2083V1P2 checks the programming of the AFE registers at a period determined by AFE Check Time DF
0xe4. The units of the check period are seconds unless the bq2083V1P2 is in sleep mode, in which case the period
is
AFE
Check Time
x
Sleep Current Time
(DF 0xe7). If the data is not correct, the bq2083V1P2 increments an
internal counter.
The CVOV flag in PackStatus() (0x2f) is set in any of the following ways:
Voltage()
≥
ChargingVoltage() + OverVoltageMargin (DF 0x5a and 0x5b)
AverageCurrent()
≥
FastCurrent + OvercurrentMargin (DF 0x5c and 0x5d)
Any cell voltage
≥
CellOverVoltage (DF 0x60 and 0x61)
The BatteryStatus() Over temperature bit is set
An example circuit using the SAFE output to blow a fuse is shown in Figure 5.

Low-Power Modes
The bq2083V1P2 enters sleep mode when the charge and discharge current is less than the threshold programmed
in
Sleep Current Threshold
DF 0xe5, the SMBus lines are low for at least 2 s, and bit 4 of
Misc. Configuration
DF
0x2a is set to zero. The bq2083V1P2 wakes up periodically to monitor voltage and temperature and to apply
self-discharge adjustment. The sleep period is set in
Sleep Timer
DF 0xe7. The bq2083V1P2 wakes up at a period
set by
Sleep Current Time
DF 0xe6 to measure current. The bq2083V1P2 comes out of sleep when the SMBus
lines go high or if the current is greater than
Sleep Current Threshold
. A rising edge on SMBC or SMBD restores the
bq2083V1P2 to the full operating mode.
Reset Conditions
On power-up the entire IC is reset and data is loaded from Data Flash to configure the SBS Data and the system.
On a partial reset (loss of VCC but RBI holds RAM valid) then a limited number of actions are taken.
These actions are the following:
The AFE registers are rewritten.
PackStatus() VDQ flag is cleared (the proposed change is not to clear VDQ).
PackStatus() EDV2 flag is cleared.
BatteryStatus() DISCHARGING flag is cleared.
The charger and alarm broadcast period is set to 10 seconds between broadcasts.
