Azoteq IQS211A
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.| Part No. | IQS211A |
