Automobile sensor high-low level control output circuit

The utility model provides an automobile sensor high and low level control output circuit comprising a conduction control circuit, the input end of which is used for acquiring a trigger signal generated by an external processing unit; the input end of the current-limiting control circuit is connected with a power supply voltage; the level output control circuit is respectively connected with the output end of the conduction control circuit and the output end of the current limiting control circuit; the input end of the reverse connection prevention circuit is connected with the output end of the level output control circuit; when the conduction control circuit receives a high level trigger signal, the output end of the anti-reverse-connection circuit outputs a high level, and when the conduction control circuit receives a low level trigger signal, the output end of the anti-reverse-connection circuit outputs a low level. According to the utility model, a high-level output circuit with high reliability is esta
