A few days ago, Vishay Intertechnology, Inc. (NYSE Stock Name: VSH) announced that its Ministry of Optoelectronics has launched a full-integrated new type of sensor-VCNL36828P to improve the efficiency and performance of consumer electronics applications.Vishay Semiconductors VCNL36828P uses vertical cavity to emit laser (VCSEL), and in the 2.0 mm x 1.0 mm x 0.5 mm small surface installation and packaging, optical diode (ASIC), 16 -bit ADC and smart dual I2C slave address.

Compared with the previous generation of solutions, the recently released sensor packaging area decreased by 20%, the current of the machine was reduced by only 5 μA, and the amount of sunshine cancel was increased by 40%to 140 klx.The detection distance of the sensor is 200 mm, a typical rated voltage 1.8 V. The device has excellent close detection performance, while reducing power consumption, improving the efficiency of limited space, and battery power application.

This new type is close to the automatic wake -up and shutdown of the sensor for smartphones and smart watch screens. In addition, you can also detect whether users wear real wireless stereo (TWS) headphones, virtual reality / augmented reality (VR / AR) helmet and smart glasses.In order to reduce the costs of these applications, VCNL36828P smart dual I2C can connect two near -sensors from the machine address, and no multi -road repeat device is required.

The programming interrupt function is convenient for the designer to set the upper and lower limit of the interrupt threshold, thereby reducing continuous communication with the microcontroller.VCNL36828P uses intelligent offset technology to eliminate string disturbances, and intelligent sustainability design ensures accurate detection and accelerate the response speed.VCSEL's wavelength peak is 940 nm, and there is no visible "red tail".The sensor meets the green standards of Rohs and Vishay, without halogen.
