Third Interrupt Register
Offset: 25h
Please be aware that writing to this register will enable/disable the corresponding
interrupts, while with reading you get the actual interrupt status and will clear the
register at the same time. It is not possible to read back the interrupt enable/disable
settings. This register is reset at a DVDD-POR.

Bit Description
0
W
Battery over-temperature interrupt setting.
0: disable
1: enable interrupt if battery temperature exceeds 45°C
The interrupt must not be enabled if the charger block and
battery temperature supervision is disabled
7
BATTEMP_HIGH
(level)
x
R
Battery over-temperature interrupt reading
0: battery temperature below 45°C
1: battery temperature was too high and the charger was
turned off. The charger will be turned on again, when the
temperature gets below 42°C
0
W
Battery end of charge interrupt setting
0: disable
1: enable
The interrupt must not be enabled if the charger block is
disabled
6
CHG_EOC
(level)
x
R
Battery end of charge interrupt reading
0: battery charging in progress
1: charging is complete, charging current is below 10% of
nominal current, turn off charger
To check end of charge again the charger has to be turned on.
5
CHG_STATUS
x
R
0: no charger input source connected
1: charger input source connected, also valid if charger is
connected during wakeup
0
W
Charger input status change interrupt setting
0: disable
1: enables an interrupt on a low to high or high to low change
of CHGIN pin.
4
CHG_CHANGED
(status change)
x
R
Charger input status change interrupt reading
0: charger input status not changed
1: charger input status changed, check CHG_STATUS
3
USB_STATUS
x
R
0: no USB input connected
1: USB input connected, also valid if USB is connected during
wakeup. The threshold can be set in the USB_UTIL register
(1Ah)
0
W
USB input status change interrupt setting
0: disable
1: enables an interrupt on a low to high or high to low change
of VBUS pin. The threshold can be set in the USB_UTIL
register (1Ah)
2
USB_CHANGED
(status change)
x
R
USB input status change interrupt reading
0: USB input status not changed
1: USB input status changed, check USB_STATUS
