Description

The Si1145/46/47-M01 is a low-power, reflectance-based, proximity, UV Index and

ambient light module with integrated single IR LED, two additional LED driver

outputs, I C digital interface, and programmable-event interrupt output. This

touchless sensor module includes an analog-to-digital converter, integrated high-

sensitivity visible and infrared photodiodes, digital signal processor, and three

integrated infrared LED drivers with fifteen selectable drive levels. The Si1145/46/47-

M01 offers excellent performance under a wide dynamic range and a variety of light

sources including direct sunlight. The Si1145/46/47-M01 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 Si1145/46/47-M01 is capable of supporting multiple-axis

proximity motion detection. The Si1145/46/47-M01 devices are provided in a 10-lead

4.9x2.85x1.2 mm QFN package and are capable of operation from 1.71 to 3.6 V over

the –40 to +85 °C temperature range.
