Overview
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.
Features  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 v01)  Failsafe firmware/hardware design  Automatic Tuning (ATI)  On-chip movement detection algorithm  Minimal external components  Standalone operation  25mm detection distance  Up to 60pF sensor load  Internal Capacitor Implementation (ICI) – reference capacitor on-chip  Configuration settings via external pins  Activation threshold  Movement filter threshold RoHS2 Compliant IQS229 DFN10 Representations only, not actual markings  Activation time-out  Supply voltage: 1.
8V to 3.
6V  Low power consumption: 30uA (sub 10uA in sleep mode)  Low profile DFN10 package (3x3) Applications  SAR detection for tablets and mobile phones  SAR detection for wireless charging stations (operating frequency > 100 MHz)  SAR detection for USB dongle-type devices  Movement detection devices (anti-theft)  Reed relay replacement  White goods and appliances  Human Interface Devices  Proximity activated backlighting  Applications with long-term activation Available Packages TA DFN10 (3x3) -20°C to 85°C IQS229 Copyright © Azoteq 2017 All Rights Reserved IQS229 Datasheet v1.
