Part Number: BQ25890 Hi,
Plesae help to check the schematic diagram for BQ25890, and Why does GEGN (pin 22) have an output voltage when VBUS_POGO is not powered and the battery (CN2001) is connected? thanks.
Part Number: BQ25890 I am working on a design with a 3.7v Li Ion battery and a requirement for both 5v and 3.3v rails. But using the BQ25890 is causing extra problems because I am having to use both step up and step down subcircuits for these different…
Part Number: BQ25890 Hello,
Currently, we are working on a project, handheld product, and the battery charger and power supply section is devloped based on Texas parts. I have attached a schematic PDF file of our design for review.
Please review…
Part Number: BQ25890 Hi, I am working on a PCB that uses USB and is to be used in a final product at scale (using the BQ25890).
Because of this the capacitance on the VBUS line cannot exceed 10uF. In this case, it is recommended to use a 1uF capacitor…
