Electronic device with protection circuit |
摘要 |
An electronic device comprises an application circuit; a first supply rail having a first electric potential; a second supply rail having a second electric potential different from the first electric potential; at least one terminal having a third electric potential, connected to the application circuit; and a protection circuit for protecting the application circuit from an injected current. The protection circuit comprises a first conductive line connected between the at least one terminal and the first supply rail, the first conductive line comprising a first switch having a first control input; and a first voltage amplifier circuit having a first input connected to the at least one terminal, a second input connected to the second supply rail and a first output connected to the first control input. |
