Hello Team,
There are two sizes of driver boards, please check the attachment for the schematic.
Main problem description:
1. At the moment of excitation, there is a chance that the driver chip DRV8328ARUYR, the upper and lower MOS tubes of a certain phase and the protection resistor will burn out.
2. In the process of robot work, the problem of DRV8328ARUYR and MOS damage has also occurred.
3. Can the DRV8328ARUYR chip use 12V power supply and MOS power independently use 48V power supply? It is easy to burn out the DRV8328ARUYR with power supply under the above conditions, but the MOS is not broken.
3. DRV8328ARUYR working under the condition of undervoltage (power supply voltage is about 5V), is there damage to the DRV8328ARUYR chip?
