The weather today is cloudy and maybe it will rain a littlebut the temp is 20 celsius hot hot hot!!!
I want to replace it because:
Near this ic is the lm339 ic. It warmed alot and the voltage at vcc pin was 2volt.
Replaced the lm78l82 and voltage is 8.2 V. Also replaced the lm339 IC but the pcb is not functional...
Suppose that this 051-9852 ic is off and if replace it will do the job.
Attached for you to cheack please is the other side of pcb
Thank you alot for helping
I have a feeling its a special.... AB may be Allen Bradley who did motor controllers... If this is the case this is probably a GAL which would need programming... BUT!! references to B9130 yield programmable power supply chip...
I would imagine it's most probably a custom chip, and is a programmable device as well - so the only source would be a direct replacement from the manufacturer.
Interesting it's a 20 pin device, which is fairly uncommon.

ust for reference i have purchased a used pcb from the garage technician that installed in first place the door before 25 years an he charged it to me for 120 Euros
I could not wait any more. The door was unlocked.
At ebay someone sells it for 50$
