IQ Switch ProxFusion Series IQS680 Datasheet Combination sensor with dual channel capacitive proximity/touch, Pyroelectric Infrared Radial sensor and metal detection capabilities The IQS680 ProxFusion IC is a multifunctional Capacitance, Pyroelectric Infrared Radial (PIR) & Inductance sensor designed for applications such as domestic energy efficient lighting applications with movement detection. The IQS680 is an ultra-low power solution designed for short or long term 2 activations through any of the sensing channels. The IQS680 operates standalone or via the I C protocol and custom configurations are stored in an on-chip EEPROM. Applications Features Unique combination of Sensors: Under Cabinet Lighting (UCL) o Capacitive Sensing Standard PIR sensor cost reduction o Inductive Sensing Smart Lights o PIR Sensing Night Lights Capacitive Sensing Battery powered PIR sensors solutions o 2pF to 200pF external capacitive load Movement detection capability o Fully adjustable sensing options o Mutual- or self-capacitance. Inductive Sensing o Distinguish between ferrous and non- ferrous metals o Only external sense coil required (PCB trace) PIR Sensing: o DSP algorithm for long range movement detection. o Automatic drift compensation. Figure 1: Under cabinet UI (PIR and Prox) Multiple integrated UIs Automatic Tuning Implementation (ATI) performance enhancement (10bit ATI) EEPROM included on-chip for calibration data and settings. Minimal external components 2 Standard I C interface (polling with sub 1ms clock stretching) Optional RDY indication for standalone Figure 2: In cabinet UI (Inductive sensor) mode operation Low Power Consumption: o 300uA (100 Hz response) Representations only, not actual markings o 10uA (10 Hz response) Supply Voltage: 1.8V to 3.6V Available Packages T DFN10-3x3x0.7 A -20C to 85C IQS680 Copyright
