Hi,
I are facing Mosfet burnout problem during Short Circuit, please let me know correct values for Rdsg,Rgs & Rchg,Rgs for Mosfet details attached.
I am using in 2 BQ7791501 in 10S configuration & using total 4 Mosfets, 2 for charging & 2 for discharging in parallel.
Everything was working good earlier, but now we have to replace Mosfets due to availability issues.
Is Rdsg=4.5k & Rgs=10Mohm ok?
Is Rchg=1k in series with Protection Circuit(Diode in Parallel 1M resistance) & Rgs=3Mohm ok?
Also Using 220E on each Mosfet Gate
Also Using Rld=450k,
& 2 100nF Capacitors in series on Source to Drain of Mosfet.
Please recommend any changes required
