Design Tip Hot Plug BMS board

ST Employee

Dear Members.

The current BMS board design has not taken in consideration all the recommendation for a Hot Plug capable design.

To make your system hot-plug resistant make sure to follow the recommendations below:

  • Change the battery connector with a hot plug capable one
  • AGND and DGND grounds shall be connected to the internal node (i.e. GND of the chip) through the drain of the MHOT FET.
  • GND_ESD and PACK_GND  grounds shall be connected to the negative terminal of the battery pack
  • All big capacitors on the VBAT line shall be tied to the GND_ESD ground.

Keep improving your designs! 😉

Best Regards,
