BQ25713B: Configuration/Typical Application when not using Power Path Feature

Part Number: BQ25713B
Other Parts Discussed in Thread: BQ25713

Do we have a Typical Application or App Note for how to configure the BQ25713 when not using the Power Path Feature?

Thanks,
Nick

  • Hi Nick,

    If I understand correctly, you would like to use the BQ25713 to charge a battery, but you will not be attaching anything to the SYS node (i.e. J6 on the EVM). 

    The default configuration settings will work fine even if SYS is floating, but you will probably want to set MinSystemVoltage (registers 0x0D/0x0C) to the minimum value of 1024 mV.  This will allow the BQ25713 to set the switching regulator voltage just above the battery voltage even when the battery is deeply depleted, removing the need for LDO mode on the BATFET, which is more efficient.

    Regards,

    Steve
