Description

The Si1102 is a high-performance (0–40 cm) active

proximity detector. Because it operates on an absolute

reflectance threshold principle, it avoids the ambiguity of

motion-based proximity systems. To achieve maximum

performance, high optical isolation (less than 10

coupling) is required between two millimeter-sized light

ports, one for the transmit LED and the other for the

Si1102. For reduced-range applications (~10 cm),

existing holes with high optical loss in a product case

may be reused as optical ports, such as display

windows, illumination light piping, camera windows,

infrared receiver windows, or headphone/microphone

holes. The detector even works without a dedicated

window if a semi-opaque plastic case is used.

The Si1102 consists of a patented, high-EMI immunity,

differential photodiode and a signal processing IC with

LED driver and high-gain optical receiver. Proximity

detection is based on measuring the reflected light from

a strobed, optically isolated LED.

The standard package for the Si1102 is an 8-pin ODFN.
