Description

The Si1141/42/43-M01 is a low-power, reflectance-based, infrared proximity 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 Si1141/42/43-M01 offers excellent

performance under a wide dynamic range and a variety of light sources including direct

sunlight. The Si1141/42/43-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 Si1141/42/43-M01 is capable of supporting multiple-axis proximity motion

detection. The Si1141/42/43-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.
