Thermoflagger™ Overtemperature Detection IC

Toshiba's Thermoflagger overtemperature detection ICs offer a different approach to detecting and protecting against abnormal heat generation. Thermoflagger is designed to be connected in series with PTC thermistors placed near heat sources.

As electronic devices become more sophisticated and power dense, heat generated by electronic components increases, which poses a risk to user safety and device health. This challenge underscores the importance of monitoring overtemperature to ensure systems are not negatively impacted by severe heat issues.

This IC works by monitoring the resistance over the connected PTC thermistors, which increases exponentially when over temperature is observed. As a result, Thermoflagger will change output states and can be read by external systems which can take appropriate actions. Various options are available such as 1 µA or 10 µA PTC current, latch type, push-pull, and open drain. The 1.6 mm x 1.6 mm ESV-packaged Thermoflagger ICs offer simple overtemperature protection with low current consumption.
