IQS620 Datasheet
Combination sensor with dual channel capacitive proximity/touch, Hall-effect sensor and
inductive sensing
The IQS620 ProxFusion^ IC is a multifunctional capacitive, Hall-effect & inductive sensor designed
for applications where any or all of the technologies may be required. The IQS620 is an ultra-low
power solution designed for short or long term activations through any of the sensing channels. The
IQS620 is fully I²C compatible and can be configured to output main trigger events on GPIOs.
