描述 Description

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.

特性 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)

应用 Application

• 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
