ams launches the TMD2636, a fully integrated proximity sensor which occupies 30% less space than currently available solutions, and so delivers transformational added value to manufacturers of True Wireless Stereo (TWS) earbuds.
Reliable proximity detection performed by one or more TMD2636 sensors enables the earbud to automatically power up when inserted in the ear and power down when removed. This maximizes power savings when the earbud is not in use while providing the best user experience.
The TMD2636 sensor module integrates a 940nm infrared (IR) Vertical-Cavity Surface-Emitting Laser (VCSEL) emitter, IR-sensing photodiodes, sophisticated control circuitry, and a clear-mold overlay in a 2.0mm x 1.0mm x 0.35mm package. The sensor has an average active-mode current consumption of 70µA and 0.7µA in sleep mode (more info).
