Circuit for signal symmetrizing in opposite phase bus drivers, especially in controller area networks in motor vehicles, has circuit to equalize switch on resistances in both paths
A circuit for signal symmetrizing in opposite phase bus drivers comprises an amplifier (TR1,TR2) in each driver path and a power transistor to send opposite phase signals (CANH,CANL) through a two-wire lead. A control circuit (10) controls the switch on resistance of the transistor in one path so that both paths have the same value.
