Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a pin control circuit and an integrated chip. Background technique [0002] In today's electronic technology field, integrated chips are widely used in many scenarios due to their advantages of complete functions and small size, and with the development of science and technology, their achievable functions are also increasing. Connection, external devices are connected to integrated chips through pins to achieve specific functions. [0003] In the application development process of the integrated chip, most pins can only realize a single function. Once the pin is occupied, the integrated chip cannot realize the corresponding function. In order to solve this problem, there is a method of multiplexing pins that use fuses to burn and blow fuses to determine their functions.

Problems solved by technology

[0003] In the application development process of the integrated chip, most pins can only realize a single function. Once the pin is occupied, the integrated chip cannot realize the corresponding function.

In order to solve this problem, there is a method of multiplexing pins that use fuses to burn and blow fuses to determine their functions. However, this multiplexing method has the problem that once the function is determined, the function cannot be changed, or it needs to be changed in conjunction with the internal software system. , without the software system can not change the function of the pin

[0004] In order to achieve low power consumption during pin multiplexing, usually the enable pins of an integrated chip can only achieve a single function. If you want to increase the function, you need to add additional pins for communication or control, or use a new chip to replace the original pin. If there is a chip, the layout of the original system circuit board needs to be re-planned, the development efficiency is low, the development cost is high, and the portability is low

[0005] Based on the above situation, the pins of existing integrated chips have a single function, which is not suitable for multi-functional application scenarios.
