Low Power Ambient Light and Proximity Sensor with Intelligent Interrupt and Sleep Modes
FN7682 Rev 0.00 November 23, 2010
The ISL29029 is an integrated ambient and infrared light-todigital converter with a built-in IR LED driver and I2C Interface (SMBus patible). This device uses two independent ADCs for concurrently measuring ambient light and proximity in parallel. The flexible interrupt scheme is designed for minimal microcontroller utilization.
For ambient light sensor (ALS) data conversions, an ADC converts photodiode current (with a light sensitivity range up to 2000 Lux) in 100ms per sample. The ADC rejects 50Hz/60Hz flicker noise caused by artificial light sources.
For proximity sensor (PROX) data conversions, the built-in driver turns on an external infrared LED and the proximity sensor ADC converts the reflected IR intensity to digital. This ADC rejects ambient IR noise (such as sunlight) and has a 540μs conversion time.
