NTC shutdown value calculation and configuration
External NTC temperature shutdown values can be calculated as shown below and configured in MCEWizard as
shown in Figure 18. For the pull-up resistor on the evaluation power board and the NTC value, please refer to
the power board’s User Guide. The value of the pull-up resistor on EVAL-M1-101TF is 4.87 kΩ (see Figure 16).

The typical value of R
NTC
at 100°C is 2.9 kΩ for the IPM IRSM505-065DA that is used in EVAL-M1-05-065D. If the
setting temperature is 100°C, the shutdown value should be 1.24 V.
