Part Number: BQ25504 Hi,
I am designing a custom PCB using the BQ25504 for direct LiPo battery charging from a small solar panel (not using the EVM). The MPPT is not working and the battery is not charging at all.
You can see my full schematic configuration…
Part Number: BQ25504 Other Parts Discussed in Thread: TMP390 , BQ25505 Tool/software: Hello,
i use the BQ25504 in a outdoor application so its important to stop charging of the battery below the freezing point.
Since the BQ25504 has no EN pin my approach…
Part Number: BQ25504 Tool/software: Dear Support Team,
I am currently utilizing the BQ25504 as a WiFi energy harvesting charger IC to charge a Li-ion battery. The circuit is divided into two main sections, and I have conducted the following verifications…
Part Number: BQ25504 Tool/software: Hi, I'm designing a wireless sensor and it runs on a LiFePO4 battery and can be charged from USB using the MCP73123 as LiFePO4 charger delivering energy into VBAT
Now I'd like to add a Solar Cell as an optional energy…
Part Number: BQ25504 Tool/software: Regarding the Current Available from the VSTOR Pin of the BQ25504
When a battery is connected to the VBAT pin (pin 14) and the system load is connected to the VSTOR pin (pin 15), what is the maximum current that can…
Part Number: BQ25504 Tool/software: The BQ25504 is neat device that i got running quite well, up to a couple of minor points i do not understand. Before we get to that my first question is if it can be that there is a small error in the functional block…
Part Number: BQ25504 Tool/software: Attached are the datasheet and EVK layout. These two documents have different layout approaches.
On datasheet page 29, the component is connected to ground using trace routing (Figure11-1) ,
while in the official…
