VCNL36828P

VCNL36828P is a small package proximity sensor with a VCSEL, low idle current, I2C interface. It is a fully integrated proximity sensor. It combines a vertical-cavity surface-emitting laser (VCSEL), photodiode, and application-specific integrated circuit (ASIC) within a single package. The VCNL36828P has been developed for proximity detection applications that require a dual server address, low power consumption, small package size, small window size, and short-range operation. In addition, given the typical rated supply voltage of 1.8V to reduce power consumption, the sensor is intended for battery-powered applications. Typical applications are smartphones and true wireless stereo (TWS) earbuds, VR/AR headsets and smart glasses, smartwatches, and touchless button/dispensing.
