Tablet - SAR detection

The IQS229 is the first device to offer a solution to meet the latest FCC SAR requirements. The unique movement detector prevents the output from clearing when the tablet or phone is held for long periods.

Austin, TX (PRWEB) December 03, 2013

Azoteq, the world leader in proximity and touch solutions, today announced the release to market of the IQS227, IQS228 and IQS229. The IQS229 is the first capacitive proximity controller specifically designed for SAR compliance in mobile devices (IEC 62209-2, FCC KDB 616217). The IQS229 incorporates a unique movement detector, which can be used in applications where proximity or touch detection is required for prolonged periods.

The IQS227 and IQS228 are new versions of the popular single channel IQS127 and IQS128 controllers. The IQS227/228 offer several improvements such as a lower operating voltage, lower power consumption, and more configurable options.

"The IQS229 is the first device to offer a solution to meet the latest FCC SAR (specific absorption rate) requirements for cell phones and tablets to reduce RF power when the device is in close contact to a human. The unique movement detector prevents the output from clearing when the tablet or phone is held for long periods," said Kobus Marneweck, VP of Marketing.

The IQS229 movement detector can also be used in many other applications such as headphones, wearable devices and medical devices to detect when the device is being used and power down when not in use.
