Hi Frederik,

BQ25505 has integrated/fixed VBATUVLO=2.2V, fixed IC high temperature shutdown and additional gate driver for external FETs used to MUX between the rechargeable secondary battery, connected at VBAT_SEC pin and primary, non-rechargeable battery.

BQ25504 has adjustable VBATUVLO with external resistors and adjustable IC high temperature shutdown.

Regards,

Jeff

Thanks Jeff.

Do I see it right that we recommend the BQ25505 instead of BQ25504 for new designs?
