Hi team,

Could you provide BQ25505 vs BQ25570 comparision table?

My customer is considering those devices for energy harvesting application (Piezo or PV).

    Hi Itoh,

    I do not have a comparison table.  The 505 and 570 have the same boost charger stage.  The 505 has MUX drivers for external FETS that switch the load between VSTOR (and rechargeable battery at BAT) output or a primary non-rechargeable battery.   The 570 has a buck converter, with input tied to VSTOR, that provides a second power rail.  The max input voltage for both is 5.0V.  The Piezo will need a rectifier in order to provide a DC voltage <5.0V to the boost charger.

    Regards,

    Jeff
