Other Parts Discussed in Thread: DRV8343S-Q1EVM, BOOSTXL-DRV8320RS, CSD18543Q3A
Hi
I found that there are capacitors used between each low sidE MOSFET' Drain and GND in DRV8343S-Q1EVM,whose Designators are C47/C48/C49 with value of 10nF(sch in MD005A).
However this is not used in BOOSTXL-DRV8320RS board.
Is it necessary for the use of drv8343s? or is it used for decrease the SHX voltage spike?
If this is needed, which value should it be set?
The 10nf capacitor is desgined for the specific MOSFET(CSD18543Q3A) or just a empirical value?
