4056 Chip

[giulio93]

Hi everyone. I have this laser saber mobo that fails (the sword is totally death). I noticed a hole in the top right chip. I can read from the chip 4056 2043. I don't know the company who mades this chip ( i don't recognise the simbol). I have some questions.
Is it the chip for the lipo charge?
Can I replace with another 4056 chip? I found a lot of chip named in that way.
I found a lot of chip 4056 but with a TP at the beginning of the name. Is the same chip?
I need some programmer to reprogram it (like bios chip) or not?
Thank you

I see it know. This should be good to replace it

My doubt stay for the 4056 chip.
for exaple this is good?

Re: 4056 Chip

it's not the charger is it?

Re: 4056 Chip

The tp4056 is a li-Ion charging ic, Here is a link to a charger module with the same brand ic https://www.amazon.com/Battery-Charg.../dp/B07PDLPNDX

The prog (pin2) is just done with a resistor to set the charge current, no programing required. It looks like a bit of hot glue on Q5 and not cracked

Ok, so the chip I linked it's ok?

I desolder the chip and this is what under. It is normal to have the connection between the Central bad and the top right and the third right?

Re: 4056 Chip

that confirms it's not a tp4056 charging chip

Is there a chance that cleaning the pads has detached the green layer? That I did damage? Cause the chip in the pics you posted is exactly the same as mine. The only difference is the "1610"

Re: 4056 Chip

It is a ME4056SPG from Microne, here is the datasheet, see page 16 (Suitable for charge status indicator, which the application not need battery’s temperature detection)

Is it a chip that manage the lipo charge ?
this one is good? https://it.aliexpress.com/item/40001...rch-mainSearch

Re: 4056 Chip

Yes, That is the same ic, the last number (1650) is a date code.

Re: 4056 Chip

Ok guys I replaced both the IC and the other chip (a diode?). Now the laser saber is charged properly and the light works fine. But I have a problem. The saber doesn't emitt any sound but when it turned off. So the speaker works. It should be make sounds when you move it quickly. Any ideas?
thanks

Re: 4056 Chip

how does it sense movement?????

Re: 4056 Chip

I dont know. but before the fail, the saber sword emits sounds when you move it quickly and when you hit something with it. Do you need a motherboard back's pic?

Re: 4056 Chip

probably need full pics of both sides and a list of whats on all the wires

Re: 4056 Chip

Hi, I have a similar problem the saber was dear, so I removed the battery and give it a push with the bench power supply reconnect the battery and for a second the saber came on, the dead, so I removed the battery and tried again to charge it again, this time I think I put the battery the other way around, but nothing happened, so I removed the battery and try to charge it again , putting the battery the correct way, but nothing, I connected the adapter no light, nothing. I did noticed that if I give the battery a bit of charge, and connect it, the 4056 gets mad hot. nothing else beside the 4056 gets hot.

I checked the datasheet of the ME4056SPG, its basically the same as the TC4056 or I'm missing something. Question, inverting the polarity should have like a diode or something to protect it? Its a removable battery. What else could get burn by inverting the polarity to check?

Thank you.
