Page 14: Bus Voltage Feedback
2.3.2 Bus voltage feedback The EVAL-M7-HVMOS-INV evaluation board includes a bus voltage feedback circuitry. It is a voltage divider. The high-side resistor is composed of two 1 MΩ resistors (R3, R6) in series, and the low-side resistor (R7) is composed of one 20 kΩ. Figure 9 shows the bus voltage feedback on the board. Make sure the low-side resistor is on this power board, which is different from some other power boards that have the low-side resistor on the control board. -
Page 15: Current Feedback Configuration
2.3.3 Current feedback configuration There are two current feedback configurations on this EVAL-M7-HVMOS-INV power board. One is a single-shunt current feedback configuration. The other is a leg-shunt current feedback configuration. The single shunt configuration is the default setting on the board. If users want to use a leg-shunt configuration, they should remove the resistors R26, R27, and R27 first. - Page 16 EVAL-M7-HVMOS-INV user guide Evaluation power board with M7 connector System and functional description According to the connection shown in Figure 11, the NTC character on the board has been tested to observe the relationship between the dropped voltage of the NTC resistor and the maximum MOSFET case temperature. In this way, users can get the hottest MOSFET temperature by measuring the NTC dropped voltage.
