SLUS500D –OCTOBER 2001– REVISED OCTOBER 2011
HPE
The HPE bit enables/disables PEC transmissions to the Smart Battery host for master mode alarm messages.
0 No PEC byte on alarm warning to host
1 PEC byte on alarm warning to host
CPE
The CPE bit enables/disables PEC transmissions to the Smart Battery Charger for master mode alarm
messages.
0 No PEC byte on broadcasts to charger
1 PEC byte on broadcasts to charger
LED
The LED bit configures the bq2060A for 4- or 5-LED indication.
0 Selects the 5-LED indication mode
1 Selects the 4-LED indication mode
SC
The SC bit enables learning cycle optimization for a Smart Charger or independent charge.
0 Learning cycle optimized for independent charger
1 Learning cycle optimized for Smart Charger
SM
The SM bit enables/disables master mode broadcasts by the bq2060A.
0 Broadcasts to host and charger enabled
1 Broadcasts to host and charger disabled
If the SM bit is set, modifications to bits in BatteryMode() do not re-enable broadcasts.
MEASUREMENT CALIBRATION
ADC
To describe how the bq2060A calculates reported battery and individual cell voltages, the following abbreviations
and designations are used:
• VCELL
1–4
= voltages at the input pins of the bq2060A
• VCELL1–4 = reported cell voltages
• Vn1–4 = voltages at the different series nodes in the battery
• Voltage() = reported battery voltage
• V
sr
= voltage across the sense resistor
The reported voltages measurements, Voltage() and VCELL1–4, may be calibrated by adjusting five 8- or 16-bit
registers in EEPROM: ADC Offset in EE0x62, ADC Voltage Gain in EE 0x66–0x67, Cell 2 Calibration Factor in
EE 0x63, Cell 3 Calibration Factor in EE 0x64, and Cell 4 Calibration Factor in EE 0x65.
