Hardware description of EVAL-M3-IM564

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.

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.

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.
