description The utility model relates to a circuit and a circuit system. The driver circuit includes a power supply node, a control node configured to receive a control signal, and an output node. The output transistor is coupled to the output node to provide a CAN bus drive signal via a current path through the output transistor. The current mirror is in a current line from the supply node to the output nodethrough the output transistor. The current line includes an intermediate portion between the current mirror and the output transistor. The current mirror is configured to switch between a first dominant mode in which the CAN bus drive signal is applied to the output node via the output transistor and a second recessive mode in which the output transistor provides a high output impedance at the output node in accordance with the control signal. As a result, a circuit and a circuit system improved in terms of cost savings and simple implementation are provided. 本申请涉及电路和电路系统。驱动器电路包括供电节点、被配置为接收控制信号的控制节点、以及输出节点。输出晶体管耦合到输出
