TDK SIM-CAL Studio Chip NTC Thermistor Simulation Tool
TDK SIM-CAL Studio Chip NTC Thermistor Simulation Tool provides part number recommendations and models up to 10 types of circuits, each with specific output characteristics. Users enter a product type and circuit condition information such as application type (automotive or commercial), NTC thermistor case size, Vin, Vout, resistor value or values, and temperature range. The tool shows which TDK part numbers match the selected conditions and the user can choose which circuits to simulate.
The circuits are classified into three groups, according to the number of resistors:
• Circuits 1 and 2 - NTC thermistor + 1 resistor: General temperature sensing circuit - R1 can be adjusted to change the sensing temperature.
• Circuits 3, 4, 5, and 6 - NTC thermistor + 2 resistors: By adding a second resistor, the output curve in the high- and low-temperature range can be adjusted. In addition, the self-heating of the NTC thermistor can be suppressed.
• Circuits 7, 8, 9, and 10 - NTC Thermistor + 3 resistors: By adding a third resistor, the output slope can be adjusted.
When the "simulate" button under the selected circuit model is clicked, a judgment is made on each of the matching part numbers. Performance graphs can also be displayed and compared for the recommended part numbers to determine which part best meets the application's needs. NTC thermistor tolerance and resistance value can also easily be modified at this point to view and check the new results.
