Abstract: A method for generating a reading signal of a sense element in at least a phase of a multiphase controller controlled by means of PWM control signals having a preset period and a duty cycle varying according to the load current and voltage of said controller, the reading signal being a digital signal having a first logic value during a reading period and a second logic value at the end of the reading period and showing a periodical trend which has a half cycle. The method provides that the value of said half cycle is so set that the reading period ends in a different instant from the switching instants of external power transistors comprised in the driving circuits of the controller phases not being read.
