IQS622 Datasheet
Combination sensor with ambient light sensing (ALS), active IR, Hall-effect and two-
channel capacitive proximity/touch sensor
The IQS622 ProxFusion^ IC is a multifunctional ambient light sensing (ALS), active IR, capacitive
& Hall-effect sensor designed for applications where any or all of the technologies may be
required. The IQS622 is an ultra-low power solution designed for short or long term activations
through any of the sensing channels. The IQS622 is fully I²C compatible and can be configured to
operate on an event mode basis to wake-up on dedicated sensors.
