is there any equivalent ic for bq24780s?

Hello everyone
I have been working on this laptop mentioned in the title, it initially had a shorted capacitor. After I replaced it, the thing started working again, but there is still another problem. The laptop was running off a charger, the battery was reporting 96% charge... but when I unplugged the charger, the laptop died. I've measured the battery voltage - 0V. I think it is locked. (Screenshot from batterymon, below).
I've ordered a new 3rd-party battery, but I think there's something wrong with it too - the laptop boots, but the battery isn't charging. Also,... -
Hi everyone,
I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.
Some history:
Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.
As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)
Now, with a new battery the system will start up and run off... -
Good evening, colleagues.
Does anyone know an equivalent or a compatible replacement for the uP9002P IC (power controller)? Alternatively, does it come under any other marking or code on different boards?
Any insight or cross-reference would be greatly appreciated. Thank you in advance!09-01-2025, 08:43 PM -
Hi All,
I'm looking for a SMPS flyback transformer TAM TO-5622, or equivalent, or any information on it? Company is Tamura Corp (https://www.tamuracorp.com). It has Primary, Secondary, and Auxiliary windings. Have emailed the company, but no info back yet. It is out of a Makita DC24SC battery charger.. This transformer has a burnt out the primary (caused by a failed MOSFET). Secondary, gave me a reading of 0.49 Ohms, and Auxiliary a reading of 0.93 Ohms. I took it to bits, thinking I might try and re-wind it, but it was more complex than I realized, and had difficulty removing... -
