Description

C3

VBAT

PWR Analog supply voltage input (2.2 V - 4.5 V)

C2

GND

PWR Ground reference

A3

VIO

PWR Digital interface supply voltage (1.6 V - 2.8 V)

B4

DP

AI/O Connected to USB D+ Data line

A4

DM

AI/O Connected to USB D- Data line

B2

DETECT

O

Hardware detection pin (open drain). 300 kΩ internal pull-down resistor. VBAT

referred.

A2

SHUTDOWN

I

Standby mode selection pin. Active HIGH. Terminates the detection and resets

the device.

A1

/OE

I Output enable for DETECT output. Active LOW.

SW detection output: High when Charger detected. Pulled high or low through

B1

STATUS/

METHOD

internal weak pull-up to 1V8V and weak pull-down.

AI/O

Detection method selection input: low for dedicated method, high for current sink

method.

B3

DEFAULT

METHOD

Hardware selection for detection method. Active only if VIO is not present.

AI Dedicated method is selected if driven low, current sink method if driven high.

VBAT referred. Do not leave floating to avoid increased power consumption.

C4

VBUS

AI

VBUS voltage comparator input. Triggers the charger detection. 6V limited voltage

when 10 V are applied externally.

C1

1V8V

O Regulator output voltage. Bypass capacitor not required.
