IQS621 Datasheet
Combination sensor with ambient light sensing (ALS), capacitive proximity/touch, Hall-
effect sensor & inductive sensing capabilities
The IQS621 ProxFusion IC is a multifunctional, ambient light sensing (ALS), capacitive, Hall-effect
& inductive sensor designed for applications where any or all of the 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 is fully I2C compatible.
