• Status flag diagnosis with current sense capability
• Protection e.g. against overtemperature and overcurrent
• Reverse polarity protection with IPD90P04P4L
• Further comments：
- Due to limited performance caused by the PCB layout， we recommend our customers to remove thecapacitance C5 for high frequency applications. It is only layout related， not refer to the device.
- The size of the DC-link capacity （C4 in schematic） with 560 μF is for most applications sufficient. But forhigh current applications， we recommend our customers to follow the design rule in our applicationnote and replace the DC-link cap with a bigger one.
- Due to the limited area of the PCB and the small DC-link cap， the demoboard shouldn’t be used forshort circuit test.
- This demoboard is designed for both sensorless applications and the application with Hall sensor. Butfor the application with sensor， please remove R36/R37/R38 and solder R18/R19/R20/R21/R22/R23/R25/R26/R27.
- Due to the limited pinout of the Arduino shield all IS pins of the three devices are connected together.According to different applications the value of R4 could be adjusted to achieve a better current sense performance.
