Abstract

L'invention concerne un circuit servant à réguler le flux de courant (IL) traversant une charge (RL) lors de la mesure du flux de courant (IL) selon le principe de la détection de courant. Le circuit présenté comporte une première paire de transistors (P1), à savoir un transistor de charge et un transistor auxiliaire (T11, T21) qui comportent un élément de raccordement de commande (G1) commun et chacun un premier élément de raccordement de section de charge (S), la charge (RL) étant reliée au premier élément de raccordement de section de charge (S) du premier transistor de charge (T11). Un dispositif de mesure (MA) est raccordé, par l'intermédiaire d'une première borne d'entrée (EK1), au premier élément de raccordement de section de charge (S) du premier transistor de charge (T11), et, par l'intermédiaire d'une seconde borne d'entrée (EK2), au premier élément de raccordement de section de charge (S) du premier transistor auxiliaire (T21), et elle présente au moins une borne de sortie (AK) au niveau de laquelle un signal de flux de courant (UA) peut être prélevé. Au moins un autre transistor de charge (T12, T1n) est monté parallèlement au premier transistor de charge (T11) et peut être commandé indépendamment du courant (IL) s'écoulant à travers la charge, par l'intermédiaire d'un autre élément de raccordement de commande (G2, Gn).
