The application relates to an identification switching circuit compatible with different
function Type-C interfaces, which comprises a master control module, a Type-C
physical interface, a feature pin identification module, a
signal switching module and a power supply switching module; a detection input end of the feature pin identification module is connected with a preset feature pin in the Type-C
physical interface, and a detection output end of the feature pin identification module is connected with an identification result
signal input end of the master control module; a first
data connection end of the
signal switching module is respectively connected with a
standard Type-C signal interface and a self-defined Type-C signal interface, a second
data connection end of the signal switching module is connected with a signal pin of the Type-C
physical interface, a
control signal input end of the signal switching module is connected with a
control signal output end of the master control module, and selective connection is carried out between the
standard Type-C signal interface and the self-defined Type-C signal interface, so that the connection requirement of the self-defined
peripheral device is considered, and the universality, adaptability and industrial application value of the interface are remarkably improved.
