Hello,

   The discharge may be useful, when system reset is implemented as full power off and

then - on (in order to decrease discharge time). 

Regards,

Yuri.

Hi M.C

Q707 and DISCHG_EN signal is used to discharge the SOC voltage when power is turned off.

You can remove it if you do not want to use it.
