• Manufacturer Part Number: 2ED100E12-F2_EVAL
• Description: Power Management IC Development Tools Eval Driver Board EconoDual
• Manufacturer: Infineon Technologies

Using the baseplate temperature and a thermal model the junction temperature can be estimated. The
complexity of the thermal model needed for this purpose depends on application and heatsinking conditions
as well as on requirements on accuracy and dynamic response. In case of a broken wire the output switches
down to 0 V. Output voltage vs. baseplate temperature is shown in Figure 14, assuming that the circuit
according to Figure 12 is used to convert the digital signal to an analog signal.

Note: This temperature measurement is not suitable for short circuit detection or short term overload and
may be used to protect the module from long term overload conditions or malfunction of the cooling system.
