ICsense, a TDK group company, is a leading supplier of analog, mixed-signal and high-voltage ASICs (Application Specific ICs). The company has filed another patent to strengthen its portfolio in innovative analog circuits. The invention allows to implement analog, floating high-voltage switches that don’t load its connected lines. Contrary to existing solutions using large resistances and thereby large time constants, this invention provides a solution with no leakage current and with a small time constant. It is particularly of interest for low-ohmic (low RDSon) switch matrix architectures for the medical, automotive, industrial and consumer markets.
