IQS229 Datasheet

Single Channel Capacitive Proximity/Touch Controller for SAR Applications

The IQS229 ProxSense^®IC is a self-capacitance controller designed for devices that are

required to meet SAR regulations. The IQS229 can detect a long term presence through

movement detection algorithms when the device (e.g. tablet or cell phone) is handled.

The IQS229 can be used in any application requiring long-term activation by animated objects.

A movement detection algorithm will indicate the presence of a user and aid in the long-term

stability of the solution. The device operates standalone and can be configured via digital

inputs.
