VCNL36828P - A Small Package Proximity Sensor With a VCSEL, Low Idle Current, I2C Interface, and Smart Dual Slave Address

Product Description

VCNL36828P 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 slave address, low power consumption, small package size, small window size, and short range operation. In addition, given the typical rated supply voltage of 1.8 V to reduce power consumption, the sensor is intended for battery-powered applications.
