发明名称 BUS DRIVER CIRCUIT
摘要 <p>A bus driver circuit for driving a bus voltage is provided. The bus driver circuit comprises: a bus line output (CANL) the bus voltage of which is driven by the bus driver circuit; a first transistor (M1) having a gate, the voltage at the gate of the first transistor (M1) determining the bus voltage at the bus line output (CANL); a first capacitor (C1) connected to the gate of the first transistor (Ml) for driving the voltage at the gate of the first transistor (M1); a first switch (S1) connecting/disconnecting the first capacitor (C1) to a first voltage source (Vgm) via a first RC network comprising at least one resistor and at least one capacitor; and a second switch (S2) connecting/disconnecting the first capacitor (C1) to a predetermined fixed potential (GND 2) for discharging the first capacitor (C1) via a second RC network comprising at least one resistor and at least one capacitor. The first switch (S1) and the second switch (S2) are complementarily driven by a signal (TxD) on a data line.</p>
