Hi Jeff,
I compared the two and found that in terms of BOM we are good. In layout, our PMID, VBAT caps and Inductor are on other side of the IC.
Sharing the Schematic for your reference. This design is for 2S but we are using 3S battery and its configuration…
Part Number: BQ25798 Hi TI experts,
Start from EVT, DVT and PVT, we seldom found some charger IC BQ25798RQMR fail units during production: 1. some are no SYS power output, and 2. some are ACDRV not driven high.
Both fail symptom we did swap tests…
Hi Scott,
Nice to hear from you again. Is this the same application we discussed previously on e2e and over regular email? We have a load switch FET selector tool available at the link below. The lowest rds(on) in 2x2mm SON is the CSD13202Q2 which is…
Hi Patty,
Thanks for the inquiry. I believe this is the same request from Scott Hsieh. I will provide the same response with the additional comments: we do not have an FemtoFETs that will meet 5mOhm on resistance. The lowest resistance FemtoFET is the…
Part Number: TPS53015 Hi,
The attached pdf is the schematic for the 3.3V output application.
My problem is no output, I had to do some troubleshooting below, but it's still not working,
1. Ensured the output(VDD_3V3_SYS) doesn't short to GND or…
Part Number: BQ25672 Problem Report
We have a system that uses a BQ25672 as a battery charger for a LiPoly 4S battery pack. Although the charger works on the BQ25672EVM, we are having problems with our design. Although the schematic is the same, the…
Part Number: TPS25751 Other Parts Discussed in Thread: BQ25792 , , BQ25751 Hi Sirs
Here is the thread we discussed before, and we find once we modify type C voltage from 9V to 15V, the type C can power our DVK board successfully, the more detail please…
