Hall-effect sensor incorporates temperature sensing
The IQS7222A is a capacitive, inductive, and Hall-effect sensor with additional temperature sensing for reference tracking.
The sensor offers a 1.71V to 3.5V voltage range, ±4000V electrostatic discharge, and +85°C max. temperature rating.
Fully I2C compatible, the device features on-chip calculations that enable multiple application options.
It can configure up to nine channels using external connections or internal sensors.
The Azoteq IQS7222A ProxFusion IC is ideal for waterproof buttons, wear detection, specific absorption rate (SAR) compliance in mobile devices, and Hall-effect dock detection.
