Abstract
In order to enable overheat protection and overcurrent protection as well as temperature detection of an inverter circuit, an inverter circuit comprises a switching circuitcomposed of a plurality of switching elements and a control circuitfor generating a control signal to be inputted into a drive circuitto control a load, a temperature detecting elementfor detecting a change in temperature of the inverter circuit is provided in a temperature detection circuit, and a temperature detection signal which changes according to a change in temperature of said inverter circuit, an overheat abnormal signal outputted upon a rise in temperature to a predetermined temperature or more, and an overcurrent abnormal signal outputted from an overcurrent protection FETare outputted via one commonly used terminal.
