Azoteq IQS229 ProxSense IC

Azoteq 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. Azoteq IQS229 ProxSense IC can be used in applications such as human interface devices, mobile devices, appliances, office equipment, and toys.
