DESCRIPTION

· The IQS625 ProxFusion® IC is a multifunctional sensor combining Hall-effect rotation sensing and dual-channel capacitive proximity/touch sensing.
· It features two Hall-effect sensors for calculating the angle of a rotating magnet parallel to the sensor.
· Fully I2C compatible, it streams the current angle interval of the magnet without requiring additional calculations.

FEATURES

· Hall effect angle sensor with on-chip Hall plates and absolute wheel interval output up to 36 intervals.
· Partial auto-calibration with continuous auto-calibration and flexible gain control.
· Capacitive sensing with full auto-tuning and adjustable sensitivity, capable of handling 2pF to 200pF external capacitive loads.
· Multiple integrated UI features including proximity/touch, proximity wake-up, event mode, and interval wake-up.
· Standard I2C interface with optional RDY indication for event mode operation.
· Low power consumption ranging from 240uA (100Hz response, Hall) to 5uA (5Hz response, capacitive).
· Operates at a supply voltage of 2.0V to 3.6V under optimal conditions.

APPLICATIONS

· Anemometer
· Dial or Selector knob
· Mouse wheel
· Measuring wheel
· Digital angle gauge
· Speedometer for bicycle
