TMG4903

General Description TMG4903 Gesture, Color and Proximity Sensor Module with mobeam™ Barcode Emulation and IR Remote Control The TMG4903 features ambient light and color (RGB) sensing, proximity detection, and IRBeam optical pattern generator capable of mobeam™ barcode emulation and IR remote control in parallel. In addition, the device integrates an IR LED and advanced LED driver, all within a low-profile and small footprint, 2.0mm x 5.0mm x 1.0mm package. The Gesture and Proximity sensing function synchronizes IR emission and detection to sense gesture and proximity events. The architecture of the engine features automatic high sample rate activation, self-maximizing dynamic range, ambient light subtraction, advanced crosstalk cancelation, 14-bit data output, 32-dataset FIFO, and interrupt-driven I²C communication. Sensitivity, power consumption, and noise can be optimized with adjustable IR LED timing and power. The gesture engine is capable of 3D detection of motion and position. Gesture interrupts are configurable to reduce I²C communication load.The proximity engine recognizes detect/release events and produces a configurable interrupt whenever proximity result crosses upper or lower threshold settings. The Ambient Light and Color Sensing function provides Red, Green, and Blue (RGB) ambient light sensing with a Clear reference (C). The color diode array has a UV/IR blocking filter and parallel ADCs to produce simultaneous 16-bit results. This architecture accurately mea...
