BQ25570: 9-15v charger

Vincenzo Pizzolante

Part Number: BQ25570
Other Parts Discussed in Thread: BQ25790, BQ25798, BQ25638

Tool/software:

Can you quickly recommend a charger supporting 9V (maybe even 15V) VBUS, 3-4A charging current with selectable battery peak voltage?

PD controller is not needed, BC1.2 optional.

Small inductor, CSP package and low cost are a big plus.

Hi Vincenzo,

What size battery? Why use BQ25570 as the part number? Is input a solar panel?

Try BQ25790. If the application allows for battery plug/unplug, then I recommend changing to BQ25798.
