OSRAM Opto Semiconductors (Sunnyvale,
CA) has released a “3 in 1” SFH 7773 digital
sensor that combines an IR LED emitter and
detector chips together, eliminating the need
to install a separate IR emitter to enable the
proximity sensor function. Apertures are integrated
into the package to reduce crosstalk.
The SFH 7773 detects objects up to a distance
of 15cm (5.9 in.) while simultaneously measuring the intensity of the ambient light.
Its power consumption is a maximum of 5μA in standby mode and 300μA in operational
mode. The integration time of the detector and, thus, the detection range
of the proximity sensor, can be selected via the I2C interface. The 5.3mm x 2.5mm
x 1.2mm sensor can also be adjusted to the transparency of the smart phone cover.
A variety of sensitivity levels is available, ranging from 3 to approximately 65.500 lux
and 0.03 to 655 lux.
