Hi team,
My customer encountered a issue when they add reverse pack voltage on BQ40Z80. They find the MOSFET will be burnt.
However they have added the reverse-protection circuit. And they used 60V VDS Mos.
It is a 6S6P project which used Li-ion cells. The charger voltage is 25.2V. So even if the pack voltage add to battery voltage it won't over 60V.
The attachment is their schematic for MOSFETs. Do you have any suggestions for this issue?
BR,
Steven
