    Battery protection circuit chip ID

    I have a lithion ion battery that has a bad chip in the protection circuit. The number on the chip is 10AH2. There is also a square box with the letters SC in it, probably the manufacturer.

    The chip is 2 layers, black on the top and white on the bottom. About 1/8"x1/4 inch with a surface mount soder connection on each side. There is an "F" on hte pcb next to it, so it could be a fuse. This chip is connected to the source terminal of a N-channel mosfet TPC8026. Tried to get pictures, but it is too small to show anything in focus with my camera.

    I have googled everything posssible with no success. Any help identifying what it is would be greatly appreciated.

              Have searched Digi-key and Mouser and can not find any SCP or thermal fuses that match this. Do you know a source?

                      Laptop battery charging circuit
                      by piernov
                      1. Some theory
                      1.1. Introduction
                      Almost every laptop has a charging circuit of some sort, that does a few things:
                      • Manages switching between AC adapter and battery power
                      • Manages battery charging and generates power rail to charge battery


                      There are 2 different designs to handle switching between AC adapter and battery power and feeding the system:
                      • Hybrid power boost (HPB) and traditional circuits without power boost (see Warning in HPB section)
                      • Narrow VDC (NVDC)

                      Texas instrument has a nice overview of these technologies with some more details at https:...

                      How to test circuit board battery connection.RS-4i sequential stimulator
                      by Crrose
                      Not sure where to post this but I have an RS-4i sequential stimulator that runs off rechargeable batteries and also has a VL2330 coin cell battery that retains the memory. If that battery doesn't hold charge or connection is bad then the unit will power on and say to recharge. Once it is charged it indicates it is charged but when you turn unit on it powers off saying to charge batteries. I replaced that coin cell battery and now it won't even indicate batteries need to be charged. I have tested the battery pack and it is fully charged at 6V but the coin cell only shows 2.97V which is a brand...

                      Vostro 3400 (LA-K033P) won't charge battery, everything else ok
                      by techfreak9356
                      I bought a Vostro 3400 motherboard (LA-K033P) to upgrade over my damaged Inspiron 5593 (LA-J091P) board. Everything else is ok except for the battery. This battery I am using now is already a replacement one since I disposed of the bloated original one. Back in the Inspiron 5593 motherboard, the battery charges fine and is identified just fine. However, with the upgraded motherboard, suddenly the replacement battery is labeled as "Not a dell battery". When I borrow a similar battery from my colleague (which did not have replacements yet), it is identified and charges just fine.

                      Nintendo Switch lite charging chip heats up and does not short circuit
                      by fab13
                      Hello everyone


                      Small technical problem on a Nintendo Switch lite
                      Here's what I noticed: the USB port has been damaged internally, with a short circuit on the power supply line to the small fuse.

                      After replacing the USB connector, the short circuit went away and I can't see any other short circuit in the whole motherboard.

                      When I charge the console, it seems to be charging: I get 15 volts and an amperage of 0.450 A.

                      Then, after a while, the amperage increases to 1.1 A and the BQ24193 charging chip starts to heat up, as evidenced...

                      by huzo
                      Hi, so the old battery was getting error stated it's capacity is starting too get low and should be replaced, so the customer bought a new one and replaced it, but the new battery was also getting this notice that it's capacity is getting low and should be replaced, so i took the laptop for testing and the battery is charging at the terminal at 8.03V , the voltage of the battery is 7.7V, and drawing around 600mA when charger is put and the laptop is off...so that should be ok... but the bios system test doesn't recognize the battery and can't do the battery test and so is the hp battery manager,...
