Hardware description of EVAL-M3-102T

5.3.1

DC bus sensing configuration

The low side resistor R4 for the DC bus sensing resistor divider on the controller board EVAL-M3-102T is 13.3kΩ,

and should be configured in MCEWizard as shown in Figure 24. For the high side resistor value, please refer to

the User Manual of the corresponding power board.

5.3.2

NTC shutdown value calculation and configuration

External NTC Temperature shutdown value can be calculated as shown below and configured in MCEWizard as

shown in Figure 25. For pull-up resistor on evaluation power board and NTC value, please refer to the power

board’s User Manual. The value of pull-up resistor on EVAL-M3-102T is 4.87 kΩ (see Figure 23).

For example, for EVAL-M3-CM615PN, the pull-up resistor on the power board is 9.1kΩ. So the total pull-up

resistance calculates to be 3.172kΩ.
