使用Thermoflagger™

Thermoflagger™ Configuration

Place PTC thermistors at locations where heat can be localized and connect them to Thermoflagger™.
When Thermoflagger™ detects abnormal heating, the PTCGOOD pin is driven Low.

Thermoflagger™ graph

When the temperature of a PTC thermistor exceeds its critical temperature,

  • Resistance of PTC thermistor increases dramatically.
  • Voltage of PTCO pin increases dramatically
    (= resistance of PTC thermistor x current of PTCO(constant))
  • the voltage at the PTCO pin exceeds a detection threshold.
  • the PTCGOOD pin is driven Low.
