Slope control circuit suitable for LIN bus, LIN interface chip and micro-processing chip

The embodiment of the invention provides a slope control circuit suitable for an LIN bus, an LIN interface chip and a micro-processing chip, and the slope control circuit comprises a differential module, a difference calculation module, a first control module and a second control module. Specifically, the differential module is used for collecting an LIN signal on an LIN bus and determining a slope corresponding to the LIN signal; the difference calculation module is used for performing difference calculation on the slope corresponding to the LIN signal and a preset slope to obtain a difference signal; the first control module is used for generating a first control signal according to the difference signal; the second control module is used for generating a second control signal according to the first control signal. In the embodiment of the invention, the slope corresponding to the LIN signal is continuously adjusted by utilizing the difference signal between the slope corresponding to the LIN signal and the
