can anybody ID a lithium charge i.c. in a 5pin sot23 package with the marking "54H3" ??

Hello everyone,
I am looking for the part number of this component so I can order it. I cannot identify it based on the marking code; I think it is an LDO IC. Can anyone determine the manufacturer's part number from the marking code?
I have uploaded images showing the dimensions and the marking code of the IC. I believe the package is a DFN-8 with dimensions of 3 mm × 3 mm × 0.9 mm.
Thank you in advance for your support -
Hello everyone.
Is there any chance somebody can find the part number of this chip or equivalent, in the attached photo?
It is from PS5 EDM-020 board, in the front usb section, near F3502.
It must be a Richtek ic, vqfn32 package style.
Thank you in advance....05-27-2024, 01:37 AM -
Hi i have a smd part with probably mark "QO 11" or "Q0(zero) 11" on it, and its package is SOT89, i doubt its KTB1260 PNP transistor, but in measuring with diode mode of multimeter it shows number 1.4 between emitter and collector pins and its not open circuit, and .59 from collector to base and .8 from emitter to base , and these numbers doesn't match a pnp transistor, i couldn't find any part number and datasheet for it, does anybody have information for that part number?
I've attached pics of this part
Thanks... -
In the Panasonic service manuals, both in the board schematics and in the part listing, the part numbers that are given are Panasonic part numbers instead of the actual part numbers.
This is especially annoying for small SMD components like diodes and transistors when you only have 1-3 digits printed on the component body.
For an example, look at the attached PDF.
Do you have a way to cross reference the Panasonic part number with the actual part number?

First of all, I hope I got this into the right section. Apologies if I did not.
I was working on my Asus ROG Strix G17 (2021) G713QM-RS96, and I guess I pre-heated the board too much replacing the DC Jack and one of the small parts came off. I looked for it on my soldering mat, and it was nowhere to be found. So now, the laptop is powered from the new DC Jack I installed, but it will not charge the battery from that jack. Only powers the hardware.
I looked at the boardview diagram in another post for the G713QM, and it looks like the diagram displays it as X450, a 4 contact...
