Hello,
I need idenfy this Chip., and prehaps where could I buy it.
This board is from topcon RL-3HA laser leveler. This plate particularly is something to do with batteries and charging.
Problem is letters on the chip have faded away, and you can barely see something.
It looks something like :
Торсол
RL CHRG NIMH
VER1-1.20
M989?33A 6???
??? 715
Given that the Chip has name printed as TOPCON, i believe this is a custom made/configured chip for topcon. I dont think you will find a replacement for this in the component market. You might need to source it from a donor board.
As stated previously this is proprietary, the QFP48 tend to be microcontrollers, even if you found the correct model this chip is based on you'd still need to potentially program the thing. Best to get a donor board or request a warranty repair.
