SI1141-A11-GM Description

Short technical summary and product information.

The Si1141/42/43 is a low-power, reflectance-based, infrared proximity and ambient light sensor with an I2C digital interface and programmable-event interrupt output. This touchless sensor IC includes an analog-to-digital converter, integrated high-sensitivity visible and infrared photodiodes, digital signal processor, and integrated infrared LED drivers.

 

It offers excellent performance under a wide dynamic range and a variety of light sources, including direct sunlight, and can also work under dark glass covers. The photodiode response and associated digital conversion circuitry provide excellent immunity to artificial light flicker noise and natural light flutter noise.

 

Key features include proximity detection adjustable from under 1 cm up to 200 cm, an integrated ambient light sensor with 100 mlx resolution possible, and industry-leading low power consumption. The device operates from 1.71 V to 3.6 V over the –40 to +85 °C temperature range and is provided in a 10-lead 2x2 mm QFN package.

 

Applications include handsets, wearables, consumer electronics, industrial automation, and display backlighting control.
