Control circuit for inductive load with control of series semiconductor switch circuit coupled to load dependent on load current

摘要

The control circuit uses a half bridge circuit with 2 semiconductor switches (T1,T2) having their load paths connected in series, with an intermediate output terminal (OUT) connected to the load. A control stage containing a current source is connected to the control terminal (G) of one semiconductor switch, with control of the series semiconductor switch circuit dependent on the load current (I2).
