DESCRIPTION
   VCNL36687S integrates a proximity and a high power VCSEL (vertical-cavity surface-emitting laser) into one small package. It incorporates photodiodes, amplifiers, and analog to digital converting circuits into a single chip by CMOS process. PS programmable interrupt features of individual high and low thresholds offers the best utilization of resource and power saving on the microcontroller. With just 20 mA pulse current, the VCNL36687S can detect the Kodak Gray Card in a distance of 20 cm, where other sensors need 200 mA.

PROXIMITY FUNCTION
• Immunity to red glow (940 nm VCSEL)
• Programmable IVCSEL sink current
• Intelligent cancellation to reduce cross talk phenomenon
• Smart persistence scheme to reduce PS response time
• 12 bits PS output data
• Programmable interrupt function for PS with upper and
   lower thresholds
• Adjustable persistence to prevent false triggers for PS

APPLICATIONS
• Proximity sensor especially for battery operated devices
• Mobile devices (e.g. smart phones, tablets) for touch
   screen locking, power saving etc.
• VR / AR headsets to detect if the headset has been put on
   or taken off
