IQS680 Datasheet
Combination sensor with dual channel capacitive proximity/touch, Passive 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 activations through any of the sensing channels. The IQS680 operates standalone or via the
I²C protocol and custom configurations are stored in an on-chip EEPROM.
