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
- 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 plus - 1 MHz)
- Supply voltage 1.71 V to 3.5 V
- Package options
- WLCSP11 (1.48 x 1.08 x 0.345 mm) - interleaved 0.35mm x 0.35 mm ball pitch
- DFN12 (3 x 3 x 0.75 mm) - 0.5 mm pitch
