Document Type and Number:
Japanese Patent JP7207576
Kind Code:
B2
Abstract:
A detection circuit including a temperature voltage generator circuit and an output circuit. The temperature voltage generator circuit generates a detection voltage corresponding to a temperature of the detection circuit based on a predetermined constant current, when a pulse signal received by the detection circuit is at a first level, and stop generating the detection voltage when the pulse signal is at a second level. The output circuit outputs a detection signal indicating whether the temperature is higher than a predetermined temperature based on the detection voltage, during a period of time between a first time that is a predetermined time period after the pulse signal reaches the first level and a second time at which the pulse signal switches from the first level to the second level, the pulse signal remaining in the first level in the period of time.
