IQS229_16 Datasheet, PDF (1/18 Pages) List of Unclassifed Manufacturers – SAR compliance in mobile devices according to the IEC 62209-2 ed1.0 standard and the FCC standard (KDB 616217 - D04 SAR for laptop and tablets

ProxSense^® Series
IQS229 Datasheet
Single Channel Capacitive Proximity/Touch Controller for SAR Applications
The IQS229 ProxSense^® IC is a self-capacitance controller designed for applications that are
required to meet SAR regulations. The IQS229 can also be used to detect a long term
presence as a movement detector. The IQS229 operates standalone and can be configured
via digital inputs.
