Tool/software:
Hello, I am working on the BMS design of a 10S battery pack, but since BQ76930 needs a mcu and the TIDA00449 reference design feeds the mcu via the REGOUT pin, it does not need a buck converter structure to reduce the battery voltage. In your documents, you wrote that the REGOUT pin will give a maximum of 20mA. In my own design, I pulled this pin to GND with 4.7uF, but for the buck converter feed, I used the C10 line, which is the highest point of the balancing circuit, as the buck input voltage because this is the part where the 10S package sees 42 V, but I have doubts about whether this use is correct. At the same time, you used the C10 line, which is the reference of the VC10X vc5x line, for the regsrc feed. Is this approach in my schematic circuit correct?
