IQ Switch
ProxFusion Series
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.
