IQ Switch ProxSense Series IQS213A Datasheet IQSwitch - ProxSense Series 3-Channel Capacitive Touch/Swipe Function Controller Overview Unparalleled Features Sub 5A* current consumption (Zero-Power electronic switch). Internal Capacitor Implementation (ICI) Reference capacitor on-chip Automatic Tuning Implementation (ATI) - Automatic tuning for optimal operation in various environments & compensation against sensitivity reducing objects IQS213A advised for applications with high load-capacitances and high sensitivity requirements. The IQS213A ProxSense IC is a fully integrated two or three channel capacitive swipe function sensor with market leading sensitivity and automatic tuning of the sense electrodes. The IQS213A provides a minimalist implementation requiring few external components, with OTP-option settings 2 (Stand-Alone mode) and programmable I C-compatible interface, which allow configuration for numerous applications. Main Features 2 or 3 Channel (Projected- or Self-Capacitance) Input device Swipe Function or Individual (Normal) Touch Electrode Implementation Variable User Interface with Adjustable Swipe Function Configuration Auto-Off and Advanced Auto-Off Warning Function Supply voltage: 1.8V to 3.6V Internal voltage regulator and reference capacitor Advanced on-chip digital signal processing OTP (One Time Programmable) options available 2 Stand-Alone GPIO Output (Default) / I C-compatible interface Low Power Modes (sub 4A*) Variable Proximity & Touch Thresholds Small outline MSOP-10 package Applications Sanitary ware, toys, office equipment Flashlights, headlamps, keychain lights Splash- / waterproof devices Swipe-to-Unlock / Wake from Standby applications Replacement for electro-mechanical switches Advantages Prevents accidental activation of conventional touch sensors Improved digital filtering to reduce external noise High immunity against aqueous substances 2 Highly adjustable device with continuous data or event driven I C communication Available options T MSOP10 A -20C to 85C IQS213A *Current consumption dependant on selected Low Power settings.
