ELECTRONIC DEVICE AND VOLTAGE DETECTION METHOD THEREOF

WIPO Patent Application WO/2024/034850

A1

An electronic device is disclosed. The present electronic device comprises: a power detection IC which, if abnormality of at least one voltage among multiple voltages is detected, outputs a detection signal having a pre-configured level; and a processor which performs an operation corresponding to the level of a detection signal output from the power detection IC, wherein the multiple voltages comprise a first voltage and a second voltage, at least one of multiple input nodes of the power detection IC is in common connection with a first resistor to which the first voltage is applied and a switching element connected to a second resistor to which the second voltage is applied, and if the switching element is turned on on the basis of the second voltage and a reference voltage applied to the switching element, the power detection IC compares the second voltage applied to the at least one input node with a threshold voltage to detect whether the second voltage is abnormal.
