Azoteq IQS7225A ProxFusion Sensor Controller

Azoteq IQS7225A ProxFusion Sensor Controllers are designed for inductive sensing applications, including relative rotational inductive sensing and/or multiple inductive buttons. These sensor controllers feature capacitive sensing capabilities that can be used to compliment the inductive sensing applications. Full I²C compatibility with configurable address, along with on-chip calculations enable the IC to respond effectively even in its lowest power modes. Azoteq IQS7225A ProxFusion Sensor Controllers are designed for a variety of applications, including wearables, waterproof inductive controls, white goods interfaces, and smart home controllers.
