Hello Furkan,

I apologize if there was confusion caused from the previous post I shared. They included 2 different schematic images (one of them was the one you were referring to), and they did explain how both worked.

As discussed in the previous post, if the PACK_EN is enabled by the MCU and a load is connected to PACK+ and PACK-, the LD_WAKE pin (that is connected to the MCU) will see a voltage and then the MCU will wake up the AFE for discharging.

If the charger is reversed, a larger voltage appears on the PACK-, goes through the charger reverse pin connected to the MCU ADC, and then informs the MCU that a reverse charger is connected. The MCU will then give an alarm.

Best Regards,
Alexis
