DESCRIPTION
APCH
0x78
[2] TEMPDAT¹
Temperature Status. Value is 0 when battery temperature is
R outside of valid range. Value is 1 when battery temperature
is inside of valid range.
APCH
0x78
[1]
INDAT
Input Voltage Status. Value is 1 when a valid input at
R CHGIN is present. Value is 0 when a valid input at CHGIN
is not present.
APCH
0x78
[0] CHGDAT¹
Charge State Machine Status. Value is 1 indicates the
R charger state machine is in EOC state, value is 0 indicates
the charger state machine is in other states.
APCH
0x79
[7] TIMRTOT
Total Charge Time-out Interrupt Control. Set both this bit
R/W
and TIMRSTAT[ ] to 1 to generate an interrupt when a total
charge time-out occurs. See the Charge Safety Timers
section for more information.
APCH
0x79
[6]
TEMPIN
Battery Temperature Interrupt Control. Set both this bit and
R/W
TEMPSTAT[ ] to 1 to generate an interrupt when the battery
temperature goes into the valid range. See the Battery
Temperature Monitoring section for more information.
APCH
0x79
[5]
INCON
Input Voltage Interrupt Control. Set both this bit and
R/W
INSTAT[ ] to 1 to generate an interrupt when CHGIN input
voltage goes into the valid range. See the Charge Current
Programming section for more information.
APCH
0x79
[4] CHGEOCIN
Charge State Interrupt Control. Set both this bit and
R/W
CHGSTAT[ ] to 1 to generate an interrupt when the state
machine goes into the EOC state. See the State Machine
Interrupts section for more information.
APCH
0x79
[3] TIMRPRE
PRECHARGE Time-out Interrupt Control. Set both this bit
R/W
and TIMRSTAT[ ] to 1 to generate an interrupt when a
PRECHARGE time-out occurs. See the Charge Safety
Timers section for more information.
APCH
0x79
[2] TEMPOUT
Battery Temperature Interrupt Control. Set both this bit and
R/W
TEMPSTAT[ ] to 1 to generate an interrupt when the battery
temperature goes out of the valid range. See the Battery
Temperature Monitoring section for more information.
APCH
0x79
[1]
INDIS
Input Voltage Interrupt Control. Set both this bit and
R/W
INSTAT[ ] to 1 to generate an interrupt when CHGIN input
voltage goes out of the valid range. See the Charge Current
Programming section for more information.
APCH
0x79
[0] CHGEOCOUT
Charge State Interrupt Control. Set both this bit and
R/W
CHGSTAT[ ] to 1 to generate an interrupt when the state
machines jumps out of the EOC state. See the State
Machine Interrupts section for more information.
APCH
0x7A [7:6]
-
R Reserved.
APCH
0x7A [5:4] CSTATE
Charge State. Values indicate the current charging state.
R See the State Machine Interrupts section for more
information.
APCH
0x7A [3:2]
-
R Reserved.
APCH
0x7A
[1] ACINSTAT
ACIN Status. Indicates the state of the ACIN input, typically
R
in order to identify the type of input supply connected. Value
is 1 when ACIN is above the 1.2V precision threshold, value
is 0 when ACIN is below this threshold.
APCH
0x7A
[0]
-
R Reserved.
: Valid only when CHGIN UVLO Threshold<V_CHGIN<CHGIN OVP Threshold.
