Azoteq IQS231A and IQS231B ProxSense® SAR Controllers are single-channel capacitive proximity/touch controllers, designed for applications where an awake/activate on the proximity function are required. The IQS231A and IQS231B are ultra-low-power solutions that use unique release and/or movement detection for applications that require long-term detection. The IQS231A and IQS231B operate standalone or I2C and feature configuration via OTP (One Time Programmable) bits. Switching from I2C to standalone during runtime is also possible in order to access all settings while offering the simplicity of a standalone output.
