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. IQS211B offers alternate hardware with identical firmware to the IQS211A. IQS211B hardware offers improved temperature response and low temperature range.
