IQS231A & IQS231B ProxSense SAR Controllers

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.
