I have two sets of this phone (actually one base is BS230 and the second one is BS260 which uses the same PSU but it also provides callerID and answering machine) but no power supply and I am trying to find information about the phone to make a new one.
All the information I got right now came...
iI already had success with an Si4835 that I removed from a dead laptop motherboard. It is a P-Channel of course but it is SOIC-8 package. It doesn't even get warm! I already ordered a few Si2307 to test. That was the only one in stock and I know it is a little small but I think it will do. If...
I already tried this. A1 and A1W are the same BAW56 component. Before checking what was going on with the pins I tried connecting two 1N4148 diodes but of course it didn't work! First of all BAW56 can't carry such currents and secondly it does not make any sense considering the pin...
First of all, thank you all for your answers!
Yes, I mean the Vcc, the + pole of the battery, call it how you want! Vss is how microchip calls it in the datasheets, that's why I used it like this.
I will try a Si2312 and see if it works!
Hello,
The SMD mark is A1VV and it is a SOT-23 (3 pin) package. I couldn't find this code anywhere, nor even Google recognizes it. I found a 2011 SMD Codes Catalog and it ain't there either. The only A1 is an SMD with a common anode pair of small signal diodes.
The device was an electronic...
