Circuit for current limiting of voltage-controlled load has differential amplifier that compares load current dependent voltage with control voltage formed by integrating output

摘要

The circuit has a transistor (T) in the load (M) current supply path, a voltage control device (SR) that controls the transistor depending on at least one control parameter so a control parameter(s) dependent voltage is applied to the load, a load current measurement device and a current limiter unit (1) with a differential amplifier (2) that compares a load current dependent voltage with a control voltage formed by integrating (3) its output.
