Sensore di prossimità CI Digitale, 10-Pin, rilevamento 1 to 50cm, 1,71 V → 3,6 V, QFN

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.

- Rilevamento di prossimità regolabile da 1 cm a oltre 50 cm
- Fino a 3 driver per LED indipendenti
- 15 impostazioni di corrente da 5,6 mA a 360 mA per driver
- Larghezza di impulso driver per LED di 25,6 μs
- Elevata immunità EMI senza contenitore schermato
- Basso consumo energetico
