Hello User,

The BQ78350 can only be sent a SMBus command to wake-up if using the ManufacturerAccess() SLEEP mode command, else the device will WAKE with any SMBus communication. Read Section 8.3.1 Device Sleep and 8.3.2 ManufacturerAccess() MAC Sleep of the Technical Reference Manual (TRM) for more detailed information on SLEEP mode conditions.

See Section 17.2 of the TRM for a list of ManufacturerAccess() commands.

Best Regards,

Luis Hernandez Salomon
