Abstract
An overheat protection circuit has an NPN transistor, a power terminal to which a supply voltage is applied, a transmission path by which the supply voltage is transmitted from the power terminal to the collector of the NPN transistor without passing through a current source, and an output voltage generator that generates an output voltage commensurate with the base-emitter voltage of the NPN transistor.
