types of gatekill input source (as shown in Figure 25). Either input source, iMOTION ™ control IC will stop the
motor when the gatekill signal is active.
In order to get high power output for this MADK board, the board uses a very low resistance R
shunt
with 10 mΩ.
The inverter overcurrent protection signal (gatekill) comes from an external comparator (U8). The ITRIP of IPM
is not used any longer.
But please note that if the comparator is selected for gatekill input source, the external gatekill signal will not
be used. And the current-sensing signal I_Shunt will be compared by the internal comparator with the “Gatekill
Comparator Reference” value set in MCEWizard only.

4.3 Thermistor/NTC characteristics and protection calculation
This board provides thermistor/NTC output on pin 15 of the 30-pin connector J3. Temperatures can be
calculated by resistor measurement.
4.3.1 CIPOS ™ internal NTC – thermistor characteristics
The thermistor characteristics for CIPOS ™ Mini IPM with built-in NTC are listed in Table 7.
