ams OSRAM has developed the AS8579, a high-precision capacitive sensor that is specifically designed to detect changes in capacity within different applications. The capacitive sensor measures the impedance that originates between a conducting surface, such as a metallic object, and human touch. The IC captures the current of the metallic object and applies advanced algorithms to determine the capacitive and resistive information. This outcome information can be read through an SPI interface, which can also be used to configure the IC.
The AS8579 capacitive sensing IC provides a multitude of diagnostic features, meeting standard functional safety requirements. The sensor is capable of distinguishing between hands-on and hands-off applications in an electromagnetic environment with high magnetic disturbances. For instance, this sensor can detect if a driver's hand is on the steering wheel or not, allowing for enhanced safety features.
The AS8579 is available in a SSOP24 package and operates at a supply voltage of 5 V. It is specifically designed to function in an electro-magnetic environment (EMC) with high magnetic disturbances, providing reliable and robust performance even in challenging operational environments.
In summary, ams OSRAM's AS8579 capacitive sensor accurately detects changes in capacity within different applications. It captures the current of a metallic object and applies advanced algorithms to determine the capacitive and resistive information. The sensor provides high-precision performance and diagnostic features for functional safety requirements, and it is capable of functioning in an electro-magnetic environment with high magnetic disturbances. The sensor is available in a SSOP24 package and operates at a supply voltage of 5 V.
