0 = Current through R1 is at its limit (I
BATT
= I0).
1 = Current through R1 is less than its limit (I
BATT
< I0).
Always returns 1
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).

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.
0 = THM voltage < 75% of REF voltage
1 = THM voltage > 75% of REF voltage
0 = THM voltage < 91% of REF voltage
1 = THM voltage > 91% of REF voltage

0 = ChargingVoltage( ) value is valid for MAX1647.
1 = ChargingVoltage( ) value exceeds what MAX1647 can actually deliver.
0 = ChargingCurrent( ) value is valid for MAX1647.
1 = ChargingCurrent( ) value exceeds what MAX1647 can actually deliver.

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.

No
0 = THM voltage > 5% of REF voltage
1 = THM voltage < 5% of REF voltage
Always returns ‘0’
0 = Ready to charge a smart battery
1 = Charger is off; IOUT current = 0mA; DLO = PGND; DHI = LX

No
0 = BATT voltage < 89% of DCIN voltage
1 = BATT voltage > 89% of DCIN voltage
BATTERY_PRESENT

No
0 = No battery is present (THERMISTOR_OR = 1).
1 = A battery is present (THERMISTOR_OR = 0).
AC_PRESENT

No
0 = VL voltage < 4V
1 = VL voltage > 4V
