IQS223

IQ Switch® ProxSense® Series Azoteq IQS223 DATASHEET 3 Channel capacitive proximity and touch controller with flick or swipe and tap & hold gesture outputs The IQS223 ProxSense® IC is a 3-channel self/projected capacitive proximity and touch controller with best in class sensitivity, signal to noise ratio and power consumption. Other features include automatic tuning of the sense electrodes, internal reference capacitor and an internal regulator to reduce total system cost. RoHS & Reach Compliant Main Features > 1 Global proximity wake-up channel (CH0) > 3 Self or projected channel capacitive controller > 4 GPIO gesture output pins (80ms pulses; Active high) > 2 GPIO strap option input pins for sensitivity selections > Configurable 1-dimensional flick or swipe gesture detection with individual direction output pins > Tap and hold gesture recognitions and output > 72Hz normal power (maximum) sampling rate > On chip noise filters and calibration algorithm > Automatic adjustment for optimal performance (ATI) > Automatic drift compensation > User selectable proximity and touch thresholds > Long proximity range with combined sensor pin charging QFN(3x3)-16 package Representation only > Low power options for extensive power saving or wake-up response, suitable for battery applications > Supply voltage range: 1.8V to 3.3V > Less than 5µA active sensing in low power mode > Less than 200µA normal mode operation at 72Hz sampling rate Applications > Mechanical key...
