Overview

The Silicon Labs Si1141/42/43 combines an active optical reflectance proximity detector with an ambient light sensor and an infrared LED into a single 10-Pin QFN package. Their dual port operation enables reliable proximity detection for moving as well as stationary objects.The Si1141 has 1 LED driver with an Integrated IR LED - RS 8920016.The Si1142 has 2 LED drivers with and integrated IR LED - RS 8920025.The Si1143 has 3 LED drivers with and integrated IR LED - RS 8920028.With the Si1143, locate three infrared LEDs in an L-shaped configuration to enable triangulation of an object and in turn, via host software, creating a gesture based user interface.These modules have photodiodes which can be used to measure both visible and infrared light. Detect levels as low as 6 lux.

- Adjustable proximity detection from 1 cm to over 50 cm- Up to 3 independent LED drivers- 15 current settings from 5.6 mA to 360 mA per driver- 25.6 μs LED driver pulse width- High EMI immunity without shielded packaging- Low power consumption
