Azoteq IQS620A ProxFusion Sensor IC
Azoteq IQS620A ProxFusion® Sensor IC integrates multiple sensor technologies onto a single chip. The IQS620A offers dual direction Hall-effect sensing, along with capacitive touch sensing, and two level inductive sensing. The IQS620A is designed for applications where any or all of these technologies may be required. The IQS620A is an ultra-low power solution designed for short or long term activations through any of the sensing channels. The IQS620A sensor is fully I2C compatible and can be configured to output main trigger events on GPIOs.
