KUALA LUMPUR, May 16 (Bernama) — Toshiba Electronic Devices & Storage Corporation (Toshiba) has launched the first two products in its Thermoflagger over-temperature detection IC series namely, “TCTH021BE” and “TCTH022BE”, which does not have a latching function for the FLAG signal when it detects abnormal states; and have a latching function, respectively.
According to Toshiba in a statement, the products detect temperature rises inside electronic equipment in a simple circuit configuration with positive temperature coefficient (PTC) thermistors.
For electronic equipment to perform as specified, their semiconductors and electronic components must operate within design parameters.
Temperature is one crucial parameter, especially if the internal temperature becomes higher than that assumed during the design process. This can be a major problem in respect of safety and reliability, and requires an overheating monitoring solution to detect any rise in temperature.
The new Thermoflagger ICs are used in combination with PTC thermistors that change their resistance values according to the temperature.
Both products detect changes in the resistance value of a PTC thermistor placed close to heat sources, and output FLAG signals to indicate over-temperature, while connecting PTC thermistors in series realises over-temperature detection for multiple locations.
Thermoflagger ICs allow users to configure over-temperature detection for an entire electronic product easily, and help to reduce its size and power consumption.
An advanced semiconductor and storage solutions supplier, Toshiba will continue to develop Thermoflagger ICs with various functions.
