Summary: | A ringing suppression circuit applicable to a transmitter module in a controller area network is provided, which includes a CANH driver circuit, a CANL driver circuit, a first operable circuit transmitting a CAN high signal, a second operable circuit transmitting a CAN low signal, and a termination component connected between the first operable circuit and the second operable circuit. By sequentially turning on a first, second, and third transistor of the CANH driver circuit and sequentially turning on a fourth, fifth, and sixth transistor of the CANL driver circuit, conventional ringing phenomenon is effectively suppressed. A plurality of transistors may also be configured for implementing the CANH driver circuit or the CANL driver circuit for further reducing a glitch. The transmitter module employing the proposed ringing suppression circuit is able to pull the bus to a recessive state and meanwhile suppress the ringing and improve the maximum data rate. |
