ProxSense® Series
IQS211A Datasheet
Single Channel Capacitive Proximity/Touch Controller with movement detection
The IQS211A ProxSense® IC is a self-capacitance controller designed for applications where
an awake/activate on proximity/touch function is required. The IQS211A is an ultra-low power
solution that uses movement detection for applications that require long term detection. The
IQS211A operates standalone or I2C and can be configured via OTP (One Time
Programmable) bits.
