Semtech Launches Smart Proximity Sensor for Short-Range Human Presence Detection & SAR Regulations in Mobile & Tablet PC Applications
SX9300 device delivers capacitive sensing with proximity feature and human body detection versus inert object discrimination
Camarillo, California - July 24, 2012
Semtech Corporation. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the SX9300, an ultra-low power capacitive proximity sensor with on-chip Specific Absorption Rate (SAR) engine for human body detection. Semtech is the first to provide a robust and cost effective proximity sensor with true discrimination between a human body and inert material. This unique feature enables mobile and tablet PC manufacturers to comply with SAR regulation for optimized data & voice communication quality of service.
The SX9300 platform is part of Semtech’s touch Interface family. This high sensitivity-sensing device features a dual-channel design with built-in human body discrimination on two distinct sets of sensors. This configuration is optimized for multiple axis proximity detection with very tiny sensor areas. SX9300 is intended for handheld connectivity devices requiring SAR regulation compliance such as mobile and tablet PC devices with 3G/4G/WCDMA mobile connectivity and Wi-Fi/mobile hotspots.
"Semtech is positioning its touch Interface products within the fast growing markets of handheld connected devices. Users expect continuous wireless connectivity; still the population is concerned by limiting radio energy absorption in the body. Controlling such radio energy requires human body proximity detection” said Marc Pegulu, Senior Marketing Director for Wireless and Sensing at Semtech. “Unlike other capacitive proximity solutions, Semtech offers a very reliable discrimination in detecting a human body versus an object. Our solution not only offers our customers products a com pliancy to health & safety regulations, but it also enables optimum wireless connectivity experience to the user”.
The SX9300 is offered in a space-saving 3mm x 3mm thin 20-QFN package. Semtech provides a variety of small form factor sensor reference designs especially adapted to tablet PCs. Semtech guarantees all of these devices to operate over the extended (-40°C to +85°C) temperature range.
