Part Number: BQ25619 Hello team, My customer has a question about overcurrent protection of BQ25619. He understood from the datasheet that IINDPM can be used for overcurrent protection. But he is concerned with BQ25619 behavior of Buck converter part when …
Part Number: BQ25619 Hi,
We want to use the PMID output to feed an external circuit.
We understand that when external voltage is applied to VBUS, the device switches from Boost mode to charging mode.
1- We want to know if is there any current limitation…

Part Number: BQ25619 Hi,
I am trying to understand the battery depletion threshold values of BQ25619.
I refer to page 9 of SLUSDF8B.PDF (June 2019).
I have a BQ25619 conected to a Li-Ion cell and when the cell voltage drops below 2.60V, the BQ25619 turns…
Part Number: BQ25619 Hi Sir,
Can we fully disable the BQ25619?
I found when we pull high /CE to disable the charger, it seems like the SW pin still has 3.6V output when VBUS exists. Can we fully disable the charger IC and no any feature work when Vbus…
