Hardware description of EVAL-M3-CM615PN

If the setting temperature is 100°C, the shutdown value should be 2.75V. If the setting temperature is 85°C, the

shutdown value should be 2.87V.

Auxiliary power supply

Figure 29 depicts the schematic of the auxiliary power supply for the Eval-M3-CM615PN board. The circuit

includes a LNK306 that is used to generate 15 V directly from the DC bus. VCC is connected to the gate drivers

inside the CIPOS™ IPM.

Figure 29 Power supply section of the Eval-M3-CM615PN evaluation board

The linear voltage regulator IFX1117ME V33 generates 3.3 V from 15 V power supply VCC. The 3.3 V power supply

is used in the PFC overcurrent comparator circuit and overtemperature hardware protection circuit. Both VCC

and 3.3 V are also present on the 30 pins iMOTION™ MADK-M3 interface connector J3 to power circuitry on the

control board.
