Title:
CIRCUIT STRUCTURE FOR ACHIEVING MULTIPLEXING OF PIN OF CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/105247
Kind Code:
A1
Abstract:
A circuit structure for achieving multiplexing of a pin of a circuit, comprising an MCU module, a temperature sensing circuit, and a functional module circuit. An output end of the temperature sensing circuit is connected to an enable signal port of the MCU module; the output voltage of the temperature sensing circuit is always higher than a threshold voltage of an enable signal; the MCU module is connected to the functional module circuit. Thus, the problem of multi-functional multiplexing of a single pin is solved, such that output and input signals of analog signal can share a pin.
