IR SENSOR FOR TOUCHLESS PROXIMITY

July 2013

GENERAL DESCRIPTION

The IS31SE5001 is a low-power, reflectance-based

infrared light sensor with advanced signal processing

and digital output. The sensor can detect making

touchless motion possible.

The IS31SE5001 uses one infrared LED and an

internal receiver which pick up the reflectance signal

to perform touchless motion detection. When

proximity motion happens, the flag bit in status

generated to inform the master to read the flag bit

through I2C interface.

IS31SE5001 is available in QFN-8 (2mm × 2mm). It

operates from 2.7V to 5.5V over the temperature

range of -40°C to +85°C.

FEATURES

 Supply voltage from 2.7V~5.5V

 400kHz I2C compatible interface

 1µA shutdown current

 0.6mA low supply current

 Detection range can be adjusted

 Integrated signal processing and digital output

 Auto interrupt clear

 Package in QFN-8 (2mm × 2mm)

APPLICATIONS

 Smart phones/GPS/MID/PAD/MP3

 Lighting/switch controller/

household electrical appliances

 Toys/game machine
