Abstract
An integrated circuit with multi-functional parameter setting and a multi-functional parameter setting method thereof are provided. The multi-functional parameter setting method includes the following steps: providing the integrated circuit, wherein the integrated circuit includes a multi-functional pin and a switch unit, wherein the multi-functional pin is coupled to an external setting unit, and the switch unit includes an operational amplifier; sensing a programmable reference voltage of the external setting unit through one operation of the switch unit and executing a first function setting according to the programmable reference voltage; and sensing a programmable reference current related to the external setting unit through another operation of the switch unit and executing a second function setting according to the programmable reference current, wherein a value of the programmable reference current is related to the programmable reference voltage.
