The AS8579 is a capacitive sensor that detects the change of capacity in different applications. The capacitive sensor measures the relative change of the impedance (RealCapSense, due to our measurement principle), dependent on the circuit. This can be used for human being detection as well as many other applications The IC capture the current of a metal object and applies algorithms to determine the capacitive and resistive information (Impedance). This information can be read via SPI Interface that can be also used for IC configuration. This high precision performance sensor also supports a multitude of diagnostic features that meet standard functional safety requirements up to ASIL B. The capacitive sensing IC is specifically designed to work under high electromagnetic disturbances (EMC). With this approach, the sensor can distinguish in a hands-on application if for example, a steering wheel is touched or not. The AS8579 is available in an SSOP24 package and operates at a supply voltage of 5 V.
Applications
Autonomous driving applications e.g.: Hands on steering wheel detection
Detection of any human presence inside a vehicle
Detection of any human presence exterior of vehicles e.g.: Automatic trunk opener (trunk opens automatically and touch-less by detection of human foot near the sensor only)
