IQS231A

The IQS231/A Single Channel Capacitive Proximity/Touch Controller for SAR applications. The IQS231/A 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
  • 10 pin DFN (IQS231A)
  • 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
