Title:
過熱保護回路
Document Type and Number:
Japanese Patent JP5540455
Kind Code:
B2
Abstract:
There is provided an overheating protection circuit, including a temperature-variable voltage generating unit generating a temperature-variable voltage by adding a temperature-proportional voltage increasing with an increase in temperature and a first turn-on voltage decreasing with an increase in temperature; and an overheating prevention signal generating unit comparing the temperature-variable voltage and a second turn-on voltage decreasing with an increase in temperature to generate an overheating prevention signal, wherein the first turn-on voltage and the second turn-on voltage have the same distribution.
