IQS231B
The IQS231B is a single channel capacitive proximity/touch controller for SAR applications. The IQS231B has human movement detection and can detect human interaction during power on and a quick release. The device also features failsafe operation with a heartbeat.
Features:
- Optimized for SAR applications
- Human movement detection - distinguish between humans and inanimate objects
- Failsafe operation with heartbeat
- Quick release for preventing unwanted activations
- Minimal external components
- Standalone and I2C modes
- OTP or I2C configuration
- Optional external threshold adjustment
- Self and Projected capacitive sensing
- Synchronization input for strategic sampling windows
- Various power modes: 100Hz, 30Hz, 8Hz, 4Hz sample rates
- Pin compatible replacement solution for the IQS128
- 6 pin TSOT23-6
- 8 pin WLCSP (IQS231A)
Applications:
- SAR Sensor
- Hybrid antennas (RF and capacitive sensing combined)
- Movement sensing applications (user interaction detection, anti-theft)
- Hold detection for screen activation
- On-ear detection
Let us help you implement your IQS231B.
We’ve done it before.
If you don’t believe us test it yourself.
Includes 1x IQS231B Shield board, 3x IQS231B Stamp module and 10x IQS231B IC’s.
Connect Shield board and Stamp module to PC via CT210/A to evaluate user proximity, quick release ability and threshold input select option with GUI.
NOTE: CT210/A sold separately.
Feel free to order us around.
