Status:
Active

The IQS7221E is an on-axis Hall rotation sensor that supports up to 42 channels and two-finger gestures. It is highly flexible with ProxFusion® technology, allowing for mutual/self-capacitive sensor configuration and inductive/capacitive button input. It supports various display touch panel types and operates on a supply voltage of 1.8V to 3.5V. The device offers high-resolution coordinate outputs, automated system power modes, and I²C communication interface, making it ideal for applications like fitness bands, TWS earbuds, game controller touchpads, and headphones.
