DESCRIPTION

APCH

0x78

[0]

CHGDAT1

Charge State Machine Status. Value is 1 indicates the

charger state machine is in EOC state, value is 0 indicates

the charger state machine is in other states.

APCH

0x79

[7]

TIMRTOT

R/W

Total Charge Time-out Interrupt Control. Set both this bit

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

R/W

Battery Temperature Interrupt Control. Set both this bit and

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

R/W

Input Voltage Interrupt Control. Set both this bit and

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

R/W

Charge State Interrupt Control. Set both this bit and

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

R/W

PRECHARGE Time-out Interrupt Control. Set both this bit

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

R/W

Battery Temperature Interrupt Control. Set both this bit and

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

R/W

Input Voltage Interrupt Control. Set both this bit and

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

R/W

Charge State Interrupt Control. Set both this bit and

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]

Reserved.

APCH

0x7A

[5:4]

CSTATE

Charge State. Values indicate the current charging state.

See the State Machine Interrupts section for more

information.

APCH

0x7A

[3:2]

Reserved.

APCH

0x7A

[1]

ACINSTAT

ACIN Status. Indicates the state of the ACIN input, typically

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]

Reserved.

APCH

0x78

[1]

INDAT

Input Voltage Status. Value is 1 when a valid input at

CHGIN is present. Value is 0 when a valid input at CHGIN

is not present.

APCH

0x78

[2]

TEMPDAT1

Temperature Status. Value is 0 when battery temperature is

outside of valid range. Value is 1 when battery temperature

is inside of valid range.
