Vishay launched the industry's first highly integrated proximity and ambient light optical sensor

vcnl4000, which integrates infrared transmitter, photodiode, ambient light detector, signal processing IC and 16 bit ADC, with I2C bus interface and compact 3.95mm x 3.95mm x 0.75mm space occupying

Pennsylvania and Malvern. Before December 14, 2010, Vishay intertechnology, Inc. (NYSE Stock Code: VSH) announced, Vcnl4000, a fully integrated proximity and ambient light optical sensor, was introduced. For the first time in the industry, an infrared transmitter, photodiode, ambient light detector, signal processing IC and a 16 bit a-rule with the following DC types were combined into a small-size 3.95mm x 3.95mm x 0.75mm leadless (LLP) surface mount package. The space saving vcnl4000 supports the easy-to-use I2C bus communication interface, which can greatly simplify the design of strategic significance in a variety of consumer and industrial applications

the new vcnl4000 can be used to lock the proximity sensor of the touch screen in mobile devices such as intelligent, touch screen, PDA, GPS unit and digital camera, as well as systems such as computers, industrial equipment and displays, so as to achieve the purpose of energy saving; It can also be used as an integrated ambient light function for the contrast anchor chain tensile strength testing machine in the display/key area. The testing machine is composed of main oil cylinder, frame, auxiliary oil cylinder and clamping claw to control and adjust the light. Vcnl4000 integrates all the circuits required for these applications into one device, and there is no need for grating, infrared emitter and photodiode to maintain alignment on the optical path

the effective resolution of proximity detection of the sensor is 16 bits, ensuring excellent resistance to crosstalk. When other products can only detect objects at the farthest 100mm, the programmable LED driving current of vcnl4000 is 10ma~200ma (increasing by 10mA), so that the farthest detection distance can reach 200mm. By modulating the signal, the device can suppress the interference of ambient light very well

vcnl4000 has built-in ambient light photodiode with sensitivity close to human eyes. The 16 bit dynamic range enables the device to detect ambient light with 0.33lux ~ 22klux bending strength falling with the increase of filler. The sensor can suppress the flicker light noise of 100Hz and 120Hz

the standby current of the device is only 1.5 A, and the power supply voltage of 2.5V ~ 3.6V and I2C bus voltage of 1.7V ~ 5V are used. The humidity sensitivity (MSL) of the sensor is 4, and it can work in the temperature range of -25 ℃ ~ +85 ℃. Vcnl4000 complies with ROHS directive 2002/95/ec and WEEE 2002/96/ec, is halogen-free and compatible with lead-free welding

vcnl4000 can now provide samples, which will be mass produced in January next year. The supply cycle of bulk orders is ten weeks
