IQS318
The IQS318 ProxFusion® IC is a standalone and I²C-sensing device for single-channel proximity or touch-sensing requirements. The sensor is configurable via external input pins, and on-chip calculations enable the IC to respond effectively in various use cases.
Main Features
- Multiple user interface options:
- Single-channel I²C / standalone inductive switch (with long-term activation: IQS318-0xx)
- Single-channel I²C / standalone inductive button / single-level trigger (IQS318-1xx)
- Single-channel I²C / standalone inductive snap button (IQS318-2xx)
- Single-channel I²C / standalone self-capacitive switch (with long-term activation: IQS318-5xx)
- 1 (self) / 2 (inductive) external sensor pad connection
- DYCAL™ 2 solution: The IQS318-0xx and IQS318-5xx offers a dynamic calibration UI with intelligent hysteresis for long-term detection
- Built-in basic functions:
- Automatic tuning
- Noise filtering
- Debounce & hysteresis
- Built-in signal processing options:
- Single I2C touch/proximity output
- Single standalone touch output
- Design simplicity:
- Configurable channel sensitivity, sample period, threshold, and charge transfer frequency using external input pins
- One-time programmable settings for custom IC configuration (MOQs apply)
- I²C debugging interface with IRQ/RDY (up to Fast Mode Plus – 1 MHz)
- Supply voltage: 1.71 V to 3.5 V
- Package options:
- WLCSP11 (1.48 × 1.08 × 0.345 mm) – interleaved 0.35 mm × 0.35 mm ball pitch
- QFN20 (3 × 3 × 0.55 mm) – 0.4 mm pitch
Applications
- General-use button/switch
