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.
