Azoteq IQS621 ProxFusion Sensor
Azoteq IQS621 ProxFusion™ Sensor integrates multiple sensor technologies onto a single chip. The IQS621 offers Ambient Light Sensing (ALS), along with dual-direction Hall-effect Sensing, Capacitive Touch Sensing, and two level Inductive Sensing. The IQS621 is designed for applications where any or all of these technologies may be required. The IQS621 is an ultra-low power solution designed for short or long term activations through any of the sensing channels. The IQS621 sensor is fully I2C compatible and can be configured to output main trigger events on GPIOs.
