IQS232

Austin, TX (PRWEB) July 06, 2012

Azoteq, the world leader in capacitive proximity solutions, today announced the release to market of the IQS232. The IQS232 is Azoteq’s latest addition to the ProxSense® family of capacitive proximity and touch controllers. The IQS232 makes it very easy to add proximity and touch keys to an existing design since the device is stand-alone and no driver software is required. The power consumption is only 3.5 microampere, which is up to 100 times better than competitive devices.

The IQS232 uses advanced analog and digital circuitry to achieve unparalleled proximity and touch performance. The high sensitivity enables the IQS232 to work reliably through glass up to 25 mm thick and achieves proximity detection up to 250 mm. The device can operate from 1.8 to 3.6V and achieves power consumption as low as 3.5 microampere while still sensing proximity and touch. The IQS232 can also be used in I2C mode that allows for full control of the sensor functions from a host controller.

The IQS232 is Azoteq’s fourth device in the 1.8V ProxSense family with more controllers to follow in Q3 and Q4 of 2012. The expanding feature sets include stand-alone devices, self- and mutual capacitive sensors and lower cost single-channel devices in small packages.

Features:

  •     2-channel input device
  •     Proximity and touch on each channel
  •     Stand alone or I2C interface
  •     Automatic tuning to optimum sensitivity
  •     Supply voltage 1.8V to 3.6V
  •     Multiple low-power modes
  •     Internal voltage regulator and reference capacitor
  •     Large proximity-detection range
  •     Automatic drift compensation
  •     SOP-8 package

Applications:

  •     Consumer electronics – TVs, Blu-Ray players, set-top boxes
  •     White goods and appliances
  •     Office equipment, educational toys
  •     Proximity detection that enables activation of backlighting
  •     Wake-up from standby applications
  •     Replacement for electromechanical switches
  •     GUI trigger and GUI control proximity detection
Pricing and availability
The IQS232 will be priced at $0.30 in 1K quantities. Samples and production are available now from Mouser (http://www.mouser.com/azoteq). More information on the IQS232 can be obtained at http://www.azoteq.com/iqs232.
