DESCRIPTION

NAME

ADC output with 200 k

Ω / 2.2 kΩ / 620Ω of pullup

resistor (Activated only when ADC_EN = '1'). Change of

IDNO

[3:0]

0000

IDNO state will trigger assertion of INT\ output.

(Refer to Table 1)

VBUS comparator output. Change of VBUS state will

trigger assertion of INT output.

VBUS

0: VVBUS < VVBUSDET

1: VVBUS > VVBUSDET

SE comparator output (Activated only when SEMREN =

'1). Change of SEND/END state will trigger assertion of

INT\ output.

SEND/END

0x04

INT_STAT1

0: VMIC > VSEND/END

1: VMIC < VSEND/END

MR comparator output (Activated only when SEMREN =

'1'). Change of MR_COMP state will trigger assertion of

INT\ output.

MR_COMP

0: VMIC < VMR_COMP

1: VMIC > VMR_COMP

Charger detection is completed. Change of CHG_DET

state will trigger assertion of INT\ output.

CHG_DET

0: VBUS is not present or no charger is detected.

1: Charger is detected.
