Description

USB Interface

DP_HOST

D+ signal connected to the resident USB transceiver on the phone.

DM_HOST

D- signal connected to the resident USB transceiver on the phone.

Connector Interface

VBUS

Input voltage supply pin to be connected to the VBUS pin of the USB connector.

GND

Ground

DP_CON

Connected to the USB connector D+ pin

DM_CON

Connected to the USB connector D- pin

Status Outputs

CHG_DET

CMOS push/pull output connected to charger IC to indicate if a charger has been detected

(LOW=charger not detected; HIGH=proprietary charger, DCP, or CDP charger detected).

SW_OPEN

Open-drain output pin; requires pull-up resistor to I/O voltage supply (LOW=switch closed;

Hi-Z=switch open).

CHG_AL_N

CMOS open-drain output pin (LOW=VBUS is valid and charge is allowed to be drawn from VBUS;

Hi-Z=VBUS is not at a valid voltage).

Input Pin

GOOD_BAT

Input that indicates if the battery is a good battery or a dead battery (VIL=dead battery; VIH=good

battery).

Note:

Output voltage conditions are LOW = VOL and HIGH = VOH.
