Abstract
An integrated limiter and active filter constituted of: an input node; an output node; a transistor coupled between the input node and the output node; a first control circuit coupled to the control terminal of the transistor and arranged to limit the amount of current flowing through the output node to a predetermined value which is responsive to a signal received at a first reference input; a second control circuit coupled to the control terminal of the transistor and arranged to limit the voltage appearing at the output node to a predetermined value which is responsive to a signal received at a second reference input; and a third control circuit coupled to input node and arranged to provide the second reference input, the third control circuit arranged to set the second reference input responsive to the input voltage and to a predetermined maximum allowed output voltage.
