Description
The Si1141/42/43 is a low-power, reflectance-based, infrared proximity and ambient
light sensor with I 2 C 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 one, two, or
three integrated infrared LED drivers with fifteen selectable drive levels. The Si1141/
42/43 offers excellent performance under a wide dynamic range and a variety of light
sources including direct sunlight. The Si1141/42/43 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. With
two or more LEDs, the Si1142/43 is capable of supporting multiple-axis proximity
motion detection. The Si1141/42/43 devices are provided in a 10-lead 2x2 mm QFN
package and are capable of operation from 1.71 to 3.6 V over the –40 to +85 °C
temperature range.
