BQ40Z50: Keep FET ON during FW programing

damien marragonis

Part Number: BQ40Z50

Tool/software:

Hello,
Is there a way to keep DSG FET ON during firmware programing?
BMS FW will be flashed by the battery powered system.

Currently, as soon as we start programing, the DSG FET opens.

Thank you.

Hello Damien,

This happens for safety reasons. There is not a way to change this behavior.

So no way to push OTA update, that is problematic.
