Method for limiting the current injected on a micro-controller tab
The method involves activating input mode of a pin (12) of a microcontroller (10) for approaching synchronization zero crossing of alternating current (14), and activating output mode of the pin after the synchronization zero crossing is received on the pin, where the pin is associated with a clippi...

| Zusammenfassung: | The method involves activating input mode of a pin (12) of a microcontroller (10) for approaching synchronization zero crossing of alternating current (14), and activating output mode of the pin after the synchronization zero crossing is received on the pin, where the pin is associated with a clipping circuit (16) formed of diodes (18, 20) in which the current is supplied in the input mode of the pin. The pin is associated with a communication circuit (26) formed of metal oxide semiconductor transistors (28, 30) in which the current is supplied in the output mode of the pin. |
