Evaluation Kit for AS8579

The Evaluation Kit is designed to test and evaluate the features of AS8579 capacitive sensor. The Evaluation Kit includes the I&P-Box (Programmer), evaluation pcb with sensor IC, a cable and a USB-stick with all necessary software.

The AS8579 is a capacitive sensor that detects the change of capacity in different applications. The capacitive sensor measures the impedance that originates between a conducting surface (metallic object) and a human being. The IC captures the current of a metal object and applies algorithms to determine the capacitive and resistive information. The outcome information can be read through a 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. The capacitive sensing IC is specifically designed to function in an electro-magnetic environment (EMC) with high magnetic disturbances. This allows the sensor to distinguish in a hands-on application if the driver‘s hand is on the steering wheel or not. The AS8579 is available in an SSOP24 package and operates at a supply voltage of 5V.
