IQS7222C
The IQS7222C ProxFusion® IC is a sensor fusion device for various multi-button applications. The sensor is fully I2C compatible, and on-chip calculations enable the IC to respond effectively even in the lowest power modes.
Main Features
- Highly flexible ProxFusion® device
- 9 (QFN) / 8 (WLCSP) external sensor pad connections
- Configure up to 10 Channels using the external connections
- External sensor options:
- Up to 8 self-capacitive buttons
- Up to 4 self-capacitive wear detection pairs (with physical reference)
- Up to 10 projected capacitive touch/proximity sensors
- Up to 4 inductive sensor elements
- Built-in basic functions:
- Automatic tuning
- Noise filtering
- Differential measurements (reference channels)
- Debounce & Hysteresis
- Dual-direction trigger indication
- Built-in signal processing options:
- Slider output
- Wheel output
- Design simplicity
- PC Software for debugging and obtaining optimal settings and performance
- One-time programmable settings for custom power-on IC configuration
- Auto-run from programmed settings for simplified integration
- Automated system power modes for optimal response vs consumption
- I2C communication interface with IRQ/RDY (up to fast plus - 1 MHz)
- Event and streaming modes
- Customizable user interface due to programmable memory
- Supply Voltage 1.8 V (-5 %) to 3.5 V
- Small packages
