Ce componentă este?

[Florin Munteanu]

Salut. Am întâlnit o componentă despre care nu găsesc informații.  Este vorba despre circuitul integrat LGT8P22A afat într-un încărcător de acumulatori. Nu găsesc date de catalog despre el.

Eu zic ca-i un procesor/microcontroler.

De ce nu pot găsi date despre el? Unde ar trebui să caut?

[sesebe]

Dacă este Intradevar un microcontroler nu-ți folosește la nimic un datasheet pt ca Integratul chiar dacă îl găsești de cumpărat îl vei găsi fără SW, iar software-ul nu-l gaseti. Iar fără software Integratul nu valorează nimic.

Are trei pini la care scrie SDA, RST și SCK. Oare e microcontroler?

[sesebe]

Pai scoate-i schema la PCB.

"From my knowledge on the subject, the matter is as follows. The original balancer and parkside charger communicate digitally via the LGT8P22A chip (the same circuit in the battery and charger). If we change the balancer, there is no communication with the charger, so it does not start charging and the solution is to change the charger so that the LGT8P22A system is omitted from the charging process. The only risk is that the use of such a converted charger for the original battery will not interrupt the charging process, because in the original battery it is not the battery that cuts off from the charging source, but sends a signal to the source so that the source completes the process. The question is whether the charger has any protection against overcharging, I do not know, if someone checked it, please let me know. I only have original batteries and I have no way to check it yet."
