Integrated switching circuit for generating a control signal for an insulated gate bipolar transistor (IGBT)

摘要

An integrated circuit for generating a drive signal for an insulated gate bipolar transistor (IGBT) with an input terminal f control signal generated by means of a micro-controller, includes a control signal path taken from the input terminal to a contr signal processing unit. The integrated circuit has a magnetically sensitive device for electrically isolating a transmitter logi circuit device. The magnetically sensitive device specifically has a conductor loop on the input side, and a magnetic field detector elemen the output side, and more specifically is a Hall element, or an anisotropic magneto-resistive component (AMR).
