Azoteq IQS211
The IQS211 ProxSense® IC is a self-capacitance controller designed for applications where an awake/activate on proximity/touch function is required. The IQS211 uses movement detection for applications that require long term detection. The IQS211 operates standalone or I2C and can be configured via OTP (One Time Programmable) bits.| Part No. | IQS211 |
