DESCRIPTION

CHG

0xD1

SUSCHG

W/R Set 1 to force the charger into suspend state. Set 0 to allow charging.

ENVISET

W/R Set 1 to enable the changes to charger voltage and current settings.

TOTTIMO[1]

W/R

Entire cycle safe timer time-out setting. [1:0]=00 for 180 minutes, 01 for

240 minutes, 10 for 300 minutes and 11 for no time-out.

TOTTIMO[0]

W/R

Entire cycle safe timer time-out setting. [1:0]=00 for 180 minutes, 01 for

240 minutes, 10 for 300 minutes and 11 for no time-out.

PRETIMO[1]

W/R

Pre-condition safe timer time-out setting. [1:0]=00 for 40 minutes, 01 for

60 minutes, 10 for 80 minutes and 11 for no time-out.

PRETIMO[0]

W/R

Pre-condition safe timer time-out setting. [1:0]=00 for 40 minutes, 01 for

60 minutes, 10 for 80 minutes and 11 for no time-out.

OVPSET[1]

W/R

Over-voltage thresholds setting, [1:0]=00 for 6.3V, 01 for 6.5V, 10 for

6.7V and 11 for 6.9V.

OVPSET[0]

W/R

Over-voltage thresholds setting, [1:0]=00 for 6.3V, 01 for 6.5V, 10 for

6.7V and 11 for 6.9V.

0xD8

TIMR_STAT

W/R

Charge Time-out Interrupt Flag/Mask. Write this bit with TIMR_PRE[ ]

and/or TIMR_TOT[ ] to 1 to allow interrupt when charge safety timers

expire. Read this bit to get charge time-out interrupt status, read back

value is 1 when interrupt is generated and it is automatically cleared to 0

upon reading, read back value is 0 when no interrupt is generated. Also

see TIMR_DAT[ ], TIMR_PRE[ ] and TIMR_TOT[ ].

TEMP_STAT

BATT_STAT

W/R

Battery Temperature or Battery Installation Detection Interrupt Flag/

Mask. Write this bit with TEMP_POS[ ] (BATT_POS[ ]) or/and

TEMP_NEG[ ] (BATT_NEG[ ]) to 1 to allow interrupt when a battery

temperature event occurs or a battery installation event occurs. Read

this bit to get the battery temperature or battery installation detection

Interrupt status, read back value is 1 when interrupt is generated and it is

automatically cleared to 0 upon reading, read back value is 0 when no

interrupt is generated. Also see TEMP_DAT[ ], BATT_DAT[ ],

TEMP_POS[ ], TEMP_NEG[ ], BATT_POS[ ] and BATT_NEG[ ].

INPUT_STAT

W/R

Input Voltage Interrupt Flag/Mask. Write this bit with INPUT_POS[ ] or/

and INPUT_NEG[ ] to 1 to allow interrupt when CHGIN UVLO or OVP

condition occurs. Read this bit to get input voltage interrupt status, read

back value is 1 when interrupt is generated and it is automatically

cleared to 0 upon reading, read back value is 0 when no interrupt is

generated. Also see INPUT_DAT[ ], INPUT_POS[ ] and INPUT_NEG[ ].

CHG_STAT

W/R

Charge State Interrupt Flag/Mask. Write this bit with CHG_POS[ ] or/and

CHG_NEG[ ] to 1 to allow interrupt when the state machine gets in or out

of EOC state. Read this bit to get the EOC state interrupt status, read

back value is 1 when interrupt is generated and it is automatically

cleared to 0 upon reading, read back value is 0 when no interrupt is

generated. Also see CHG_DAT[ ], CHG_POS[ ] and CHG_NEG[ ].

TIMR_DAT

Charge Timer Status. Value is 1 when precondition time-out or total

charge time-out occurs. Value is 0 in other cases.

TEMP_DAT

BATT_DAT

Temperature or Battery Installation Status. Value is 1 when battery

temperature is inside of valid range or battery installation is detected.

Value is 0 in other cases.

INPUT_DAT

Input Voltage Detection Status. Value is 1 when CHGIN voltage is valid,

value is 0 when CHGIN voltage is not valid. The valid range is

VUVLO<VCHGIN<VOVP.

CHG_DAT

Charge State Machine Status. Value is 1 when the charger state

machine is in EOC state. Value is 0 in other cases.

Note:

W/R: Write and read accessible. R: Read accessible, writing to the bit does not make change to the volume.
