BQ25601: Disconnecting the battery from system and possible substitute

Part Number: BQ25601

Dear Team,

In our design we are using the BQ25601 charger with a software option to disable the BATFET, it works OK, when writing to address 0x07 bit 5 the system is disconnected from battery and switching the QON pin returns the desired voltage on SYS. However, more suitable for us would be to use this external switch to disconnect the battery from system as well, without software control. Is writing to I2C register 0x07 the only option to disable the BATFET? If so, is there maybe a replacement chip with the functionality as described?

Regards,

Krzysztof Kondratowicz
