Digital Ambient Light Sensor and Proximity Sensor with Interrupt Function

The ISL29011 is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C Interface (SMBus Compatible). This device provides not only ambient light sensing to allow robust backlight/display brightness control but also infrared sensing to allow proximity estimation featured with interrupt function.
