Table 8. ChargerStatus() Bit Descriptions
DESCRIPTION
0 = Ready to charge a smart battery
1 = Charger is off; IOUT current = 0mA; DLO = PGND; DHI = LX
Always returns ‘0’
0 = BATT voltage is limited at the voltage set point (BATT = V0).
1 = BATT voltage is less than the voltage set point (BATT < V0).
0 = Current through R1 is at its limit (I
BATT
= I0).
1 = Current through R1 is less than its limit (I
BATT
< I0).
0 = VL voltage < 4V
1 = VL voltage > 4V
0 = THM voltage > 5% of REF voltage
1 = THM voltage < 5% of REF voltage
No

This bit reports the state of an internal SR flip-flop (denoted ALARM_INHIBITED
flip-flop). The ALARM_INHIBITED flip-flop is set whenever the AlarmWarning()
command is written with D15, D14, or D12 set. The ALARM_INHIBITED flip-flop
is cleared whenever BATTERY_PRESENT = 0, or ChargerMode() is written with
POR_RESET = 1, or ChargingVoltage() or ChargingCurrent() is written.

THERMISTOR_UR
Always returns 0
0 = ChargingCurrent() value is valid for MAX1667.
1 = ChargingCurrent() value exceeds what MAX1667 can actually deliver.
0 = ChargingVoltage() value is valid for MAX1667.
1 = ChargingVoltage() value exceeds what MAX1667 can actually deliver.
0 = THM voltage < 91% of REF voltage
1 = THM voltage > 91% of REF voltage
0 = THM voltage < 75% of REF voltage
1 = THM voltage > 75% of REF voltage

This bit reports the state of an internal SR flip-flop (denoted THERMISTOR_HOT
flip-flop). The THERMISTOR_HOT flip-flop is set whenever THM is below 23%
of REF. It is cleared whenever BATTERY_PRESENT = 0 or ChargerMode() is
written with POR_RESET = 1.
