**
State at chip initial power-on.
BIT
NAME
FUNCTION
0
CHARGE_INHIBITED
0** = Ready to charge smart battery.
1 = Charger is inhibited, I(chg) = 0mA.
This status bit returns the value of the CHG_INHIBITED flip-flop.

Function disabled. Always returns zero.
Always returns a 1.
Always returns a zero.
6
CURRENT_OR
0** = The ChargingCurrent() value is valid for the MAX1645B.
1 = The ChargingCurrent() value exceeds the MAX1645B output range,
i.e., programmed ChargingCurrent() exceeds 3008mA.
7
VOLTAGE_OR
0 = The ChargingVoltage() value is valid for the MAX1645B.
1** = The ChargingVoltage() value exceeds the MAX1645B output range,
i.e., programmed ChargingVoltage() exceeds 1843mV.
8
THERMISTOR_OR
0 = THM is <91% of the reference voltage.
1 = THM is >91% of the reference voltage.
9
THERMISTOR_COLD
0 = THM is <75.5% of the reference voltage.
1 = THM is >75.5% of the reference voltage.
10
THERMISTOR_HOT
0 = THM has not dropped to <23.5% of the reference voltage.
1 = THM has dropped to <23.5% of the reference voltage.
THERMISTOR_HOT flip-flop cleared by BATTERY_PRESENT = 0 or writing a 1 into the
POR_RESET bit in the ChargerMode() command.
11
THERMISTOR_UR
0 = THM is >7.5% of the reference voltage.
1 = THM is <7.5% of the reference voltage.
12
ALARM_INHIBITED
Returns the state of the ALARM_INHIBITED flip-flop. This flip-flop is set by either a
watchdog timeout or by writing an AlarmWarning() command with bits 11, 12, 13, 14,
or 15 set. This flip-flop is cleared by BATTERY_PRESENT = 0, writing a 1 into the
POR_RESET bit in the ChargerMode() command, or by receiving successive
ChargingVoltage() and ChargingCurrent() commands. POR: 0.
13
POWER_FAIL
0 = The charging source voltage CVS is above the BATT voltage.
1 = The charging source voltage CVS is below the BATT voltage.
14
BATTERY_PRESENT
0 = No battery is present (based on THM input).
1 = Battery is present (based on THM input).
15
AC_PRESENT
0 = DCIN is below the 7.5V undervoltage threshold.
1 = DCIN is above the 7.5V undervoltage threshold.
