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 measures ambient light and enables the
calculation of illuminance, chromaticity, and color temperature
to manage display appearance.
The IRBeam pattern generator supports mobeam™ barcode
emulation and IR remote control. The engine features RAM for
pattern storage and specialized control logic that is tailored to
repetitively broadcast a barcode pattern using the integrated
LED or an external LED with a low side driver. The IRBeam engine
features adjustable timing, looping, and IR intensity to
maximize successful transmission. IRBeam is designed to
support all requirements for 1-D barcode transmission over IR
to point-of-sale (POS) terminals as well as IR remote control.
