Default value loaded by:
Read/write R R R R R R R R
Bit 7 TS_HOT:
0 = battery temperature is below high temperature threshold (45°C/50°C/55°C/60°C).
1 = battery temperature is above high temperature threshold (45°C/50°C/55°C/60°C).
Bit 6 TS_COLD:
0 = battery temperature is above low temperature threshold (0°C/5°C/10°C/15°C)
1 = battery temperature is below low temperature threshold (0°C/5°C/10°C/15°C)
Bit 5 OVP:
0 = Input overvoltage protection is not active (VAC<6.6V)
1 = Input overvoltage protection is active (VAC>6.6V)
Bit 3 CH_ACTIVE:
0 = charger is not active
1 = charger is charging the battery
Bit 2 CH_PGOOD:
0 = no input voltage at pin AC or voltage not inside the voltage range for changing
1 = power source is present and in the range valid for charging
Bit 1 CH_THLOOP:
0 = thermal loop not active
1 = thermal loop active
