DESCRIPTION
The TSSP770.. series are compact infrared detector
modules for presence
applications. They provide 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.
This component has not been qualified according to
automotive specifications.
APPLICATIONS
• Reflective sensors for hand dryers, towel or soap
dispensers, water faucets, toilet flush
• Vending machine fall detection
• Security and pet gates
• Person or object vicinity activation
• Fast proximity sensors for toys, robotics, drones, and
other consumer and industrial uses
