CM36286 Proximity and Ambient Light Sensor with Interrupt and Active Force Mode

  CM36286 integrates a proximity sensor (PS), ambient light sensor (ALS) and IR LED driver into one small package. It incorporates photodiodes, amplifiers and analog to digital converting circuits into a single chip by the CMOS process. The 16-bit high resolution ALS offers the excellent sensing capabilities with sufficient selections to fulfill most of applications whatever dark or high transparency lens design. Both ALS and PS programmable interruption features of individual high and low thresholds offers the best utilization of resource and power saving on the microcontroller. Average Mode of ambient light sensing provides with the best panel backlight management efficiently.

  For the 12\16-bit proximity sensing function, CM36286 build in the intelligent cancellation scheme that helps to eliminate cross talk phenomenon effectivitely. To accelerate the PS response time, Smart Persistence prevents the miss judgment of proximity sensing but also keep the fast response time. Active Force mode, one time trigger by one instruction, is another good approach for more design flexibility to fulfill different kind of applications with more power saving.

  The adoption of the Filtron™ technology achieves the closest ambient light spectral sensitivity to real human eye responses and offers the best background light cancellation capability (including sunlight) without utilizing the microcontrollers' resources. CM36286 provides an excellent temperature compensation capability for keeping output stable under various temperature configurations.  ALS and PS functions are easily operated via the simple command format of I2C (SMBus compatible) interface protocol. Operating voltage ranges from 2.5 V to 3.6 V. CM36286 is packaged in a lead-free 6 pin OPLGA package, which offers the best market-proven reliability quality.
