VCNL4200

VCNL4200 is a high-sensitivity long-distance proximity and ambient light sensor with an I²C. It integrates a high-sensitivity long-distance proximity sensor, ambient light sensor (ALS) with I²C Interface, and 940nm IRED into one small package. It incorporates photodiodes, amplifiers, and analogue to digital converting circuits into a single chip using a CMOS process. The 16bit high-resolution ALS offers excellent sensing capabilities with sufficient selections to fulfil most applications whether dark or high transparency lens design. It offers individual programmable high and low threshold interrupt features for best utilization of resources and power saving on the MCU. Applications include presence detection to activate displays in printers, copiers, and home appliances, collision detection in robots and toys, proximity sensing and lighting control in offices, corridors, and public buildings, parking space availability in lots and garages, proximity detection in lavatory appliances.

• Integrated modules: infrared emitter, ambient light sensor, proximity sensor, signal conditioning IC
• Operates ALS/PS in parallel structure, adjustable persistence to prevent false triggers for ALS/PS
• FiltronTM technology adoption for robust background light cancellation
• Supports low transmittance (dark) lens design
• Low power consumption I²C (SMBus compatible) interface
• Floor life: 168 h, output type: I²C bus (ALS / PS)
• Immunity to red glow (940nm IRED), intelligent background light cancellation
• Smart persistence scheme to reduce PS response time, proximity distance up to 1.5m
• Programmable interrupt function for ALS and PS with upper and lower thresholds
• Temperature compensation range from -40°C to +85°C, dimension (L x W x H) is 8.0 x 3.0 x 1.8mm
