Thermoflagger™ (Over temperature detection IC)

Toshiba's Thermoflagger™ ICs combined with PTC thermistors detects over temperature of electronic devices.
Thermoflagger™ can offer an inexpensive, low current consumption solution which can detect a wide area of abnormal over temperature conditions by connecting to several PTC thermistors. More robust over temperature protection solutions can be realized by combining Thermoflagger™ with general temperature sensor ICs.
