Control circuit for an electronic driving device of inductive loads, in particular for a device with an input signal having, at the high logic state, non optimal voltage value

摘要

A control circuit (6) for an electronic driving device (9) of inductive loads is described, comprising at least a control block (1, 10) activated by a trigger signal (V_TRIGGER) having at the high logic state non optimal voltage values and output-connected to a control terminal of a power element (TR1) of the electronic driving device (9).;The control circuit also comprises an auxiliary current generator (A) capable of delivering a current (IAUX) to be added to the current (IDRIV) outputted by said control block (1, 10) to supply a driving current IGATE.
