Title (EN) VOLTAGE CLAMP
(FR) PINCE DE TENSION
Abstract: front page image
(EN)An active over-voltage clamp system includes at least one over-voltage detector that is responsive to an input voltage and provides a first current. The system also includes a replica over-voltage circuit that provides a second current, and circuitry subtracting the second current from the first current to produce a difference current. The system further includes a differential clamp activated in response to the difference current. The differential clamp prevents the input voltage from increasing beyond a target voltage.
(FR)La présente invention concerne un système actif de pince de surtension qui comprend au moins un détecteur de surtension qui répond à une tension d’entrée et fournit un premier courant. Le système comprend également une réplique de circuit de surtension qui fournit un second courant, et une circuiterie qui soustrait le second courant du premier courant pour produire un courant de différence. Le système comprend en outre une pince différentielle activée en réponse au courant de différence. La pince différentielle empêche la tension d’entrée d’augmenter au-delà d’une tension cible.
