Overview

ProxSense® Series IQS211A/B Datasheet Single Channel Capacitive Proximity/Touch Controller with movement detection The IQS211A/B ProxSense® IC is a self-capacitance controller designed for applications where an awake/activate on proximity/touch function is required.

The IQS211A/B is an ultra-low power solution that uses movement detection for applications that require long term detection.

The IQS211A/B operates standalone or I2C and can be configured via OTP (One Time Programmable) bits.

Key Features

  • Pin compatible with IQS127D/ 128/ 227AS/ 228AS/ 231A (output types may differ) RoHS2 Compliant.
  • Automatic Tuning Implementation (ATI).
  • On-chip movement detection algorithm.
  • Forced activation when movement detected 8 pin WLCSP-8 6 pin TSOT23-6.
  • Minimal external components Representations only, not actual markings.
  • Down to 10aF capacitance resolution.
  • Up to 60pF sensor load (with effective o Runtime switch to standalone mode movement detection).
