ProxSense^® Series
IQS211 Datasheet
Single Channel Capacitive Proximity/Touch Controller with movement detection
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.
