SI1102-A-GMR - Silicon Labs Function Overview

The SI1102-A-GMR is a high-performance (0 to 50cm) Active Proximity Detector operates on an absolute reflectance threshold principle and it avoids the ambiguity of motion-based proximity systems. The detector consists of a patented, high-EMI immunity, differential photodiode and a signal-processing IC with LED driver and high-gain optical receiver. Proximity detection is based on measurements of reflected light from a strobed and optically-isolated LED.
Single-pulse sensing mode for low system power
Adjustable detection threshold and strobe frequency
Proximity (PRX) status latch enables controlling devices to avoid missing a detection
Current driven (400mA) or saturated LED driver output
