Title:
OVERHEATING PROTECTION CIRCUIT
Document Type and Number:
Japanese Patent JP2014108046
Kind Code:
A
Abstract:
To provide an overheating protection circuit.
The overheating protection circuit includes: 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. The deviation of the first turn-on voltage and the deviation of the second turn-on voltage can be the same.
