Si1146-M01-GMR Silicon Labs, 1 to 50cm 1.71 V to 3.6 V 10-Pin QFN

The Silicon Labs Si1145/46/47 combines an active optical reflectance proximity detector, an ambient light sensor, UV index 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 Si1145 has 1 LED driver with an Integrated IR LED - RS
The Si1146 has 2 LED drivers with and integrated IR LED - RS
The Si1147 has 3 LED drivers with and integrated IR LED - RS

With the Si1147, locate three infrared LEDs in an L-shaped configuration in your application 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
