Third Interrupt Register

Please be aware that writing to this register will enable/disable the

corresponding interrupts, while reading gets 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 AVDD27-POR.

Bit Description

BATTEMP_IRQ

Battery over-temperature interrupt setting.

0: disable

1: enable interrupt if battery temperature exceeds 45/55°C

The interrupt must not be enabled if the charger block and

battery temperature supervision is disabled

Battery over-temperature interrupt reading

0: battery temperature below 45/55°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 42/50°C

CHG_EOC

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

CHG_CON

0: no charger input source connected

1: charger input source connected, also valid if charger is

connected during wakeup

CHG_IRQ

Charger status change interrupt setting

0: disable

1: enables an interrupt on a low to high or high to low change

of CHGIN pin or on an EOC condition

CHG_changed

(status change)

Charger input status change interrupt reading

0: charger status not changed

1: charger status changed, check CHG_CON, CHG_EOC

USB_CON

n/a

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)

USB_IRQ

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

USB_changed

(status change)

USB input status change interrupt reading

0: USB input status not changed

1: USB input status changed, check USB_CON
