DESCRIPTION
The TSSP980.. is a compact infrared detector module for
presence sensing applications. It provides an active low
output in response to infrared bursts at 940 nm. The
frequency of the burst should correspond to the carrier
frequency shown in the parts table for presence sensing.
This component has not been qualified according to
automotive specifications.
