New VCNL36826S For Hand-Held Equipment Where Miniature Size Is Critical

Vishay VCNL36826S VCSEL Integrated Proximity Sensor combines a high-power vertical-cavity surface-emitting laser (VCSEL), a photodiode for proximity measurement, and a signal processing IC in a single package with a 12-bit ADC. The device provides proximity sensing to minimize accidental touch inputs. With a range up to 20cm (7.9″), this stand-alone component simplifies the use and design-in of a proximity sensor as no mechanical barriers are required to optically isolate the emitter from the detector. The VCNL36826S is offered in a miniature, surface mount, 2.5mm x 2.05mm leadless package (LLP) with a low 1mm profile. The device is designed to meet the low-height requirements of smartphones, mobile phones, digital cameras, and tablet PC applications.

With the standard I2C bus serial digital interface, access to the “proximity signal” is easy to attain. The programmable interrupt function offers wake-up functionality for the microcontroller when a proximity change occurs. This reduces processing overhead by eliminating the need for continuous polling
