IQS231A-00000000-TSR

Features of IQS231A

• Simple GPIO output with integrated SAR user interface
• Quick release detection significantly eliminates erroneous triggers.
• Options for rapid release of sensitivity
• Ample control for detecting in RF situations with high power
• Pin compatibility with similar packaging type devices
• Input voltage: 1.8V (-2%) to 3.6V
• Resolution of a capacitance down to 0.02 fF
• Up to 120pF of capacitive load capacity
• An external pin for threshold adjustment
• Fewest external parts possible (direct input strap)
• Independent failsafe mode
• OTP adjustments provide performance advantages while maintaining safety and passing SAR lab qualification as the default options.
• Optional I2C interface
• The master may synchronize on failsafe pulses from the synchronization output. Sense-making occurs after each pulse.
• Sensing is only carried out when synchronization input is minimal

Applications of IQS231A

•  SAR detector
• Designing integrated hybrids (RF and capacitive sensing combined)
• Applications for movement sensing (detection of user engagement, theft prevention)
• Hold detection to activate the screen.
• Ear-mounted detection
