IQS624
The IQS624 ProxFusion® IC is a multifunctional capacitance, inductance and Hall-effect sensor designed for applications where any or all of the technologies may be required. The two Hall-effect sensors calculate the angle of a magnet rotating parallel with the sensor. The sensor is fully I2C compatible and on-chip calculations enable the IC to stream the current angle of the magnet without extra calculations. The inductive sensing is suitable for the detection of metallic objects while capacitive sensing provides human touch and proximity detection.
Features:
- Hall Effect Sensor:
- On-chip Hall plates
- 360° Absolute Output
- 1° Resolution, calculated on chip
- Detect movement and the direction of movement
- Raw data: can be used to calculate degrees on an external processor.
- Wide operational range
- No external components required
- Partial auto calibration:
- Continuous auto-calibration, compensation for wear or small displacements of the sensor or magnet
- Flexible gain control
- Automatic Tuning Implementation (ATI) – performance enhancement (10 bit)
- Capacitive sensing:
- Full auto-tuning with adjustable sensitivity
- 2 pF to 200 pF external capacitive load capability
- Inductive sensing:
- Only external sense coil required (PCB trace)
- Multiple integrated UI:
- Proximity / Touch
- Proximity wake-up
- Event mode
- Wake Hall sensing on proximity
- Minimal external components
- Standard I2C interface
- Optional RDY indication for event mode operation
- Low power consumption:
- 240 μA (100 Hz response, Hall)
- 55 μA (100 Hz response, capacitive)
- 65 μA (20 Hz response, Hall)
- 15 μA (20 Hz response, capacitive)
- 5 μA (5 Hz response, capacitive)
- Supply voltage: 2V to 3.6 V1
Applications:
- Anemometer
- Dial or Selector knob
