Pin Description

Note(s):

1. When the SDA and SCL signals are swapped, the device uses a different I²C address. See the I²C Characteristics section for more details.

Pin Number

Pin Name

Description

1INT

Interrupt. Open drain output (active low). If INT is not used, tie to GND

for enhanced ESD protection.

2VDD

Supply voltage for sensor (1.8V). To enable the device to recover from

a high voltage system ESD strike, it is recommended to connect VDD

to a host GPIO pin for independent power control.

3

GND

Ground. All voltages are referenced to GND.

4

VDD3

Supply voltage for IR emitter (3.0/3.3V)

5

SCL (1)

I²C serial clock input terminal

6

SDA (1)

I²C serial data I/O terminal
