    SN0502045 datasheet

    Hi guys,i have Volvo radio to repair,it was water damaged. Now,after cleaning and removing BT module(was shorted),i can supply power to radio but i cannot switch on. I think that problem is in sn0502045 IC,is maybe some kind of voltage regulator,on coils arround are some known voltages(3,3V etc.),on one coil i meassured 0V. This area was corroded,i found also some ceramic capacitors which i suspect. I cannot find info about this chip,datasheet,nothing. Maybe someone have something usable for me
    thank in advance..

      dont believe this,they write everything there as i see from pcb,it should be some mosfet driver,probably some regulator but i need to replace damaged capatitors-for values of this components is maybe datasheet helpfull

        If that is not the ic, can you provide a picture of the ic? or case type and number of pins?
        That is likely a custom part number

            I did see some other listing that called it a voltage regulator. It could be common ic but with just a custom number, or it was customized by TI for the radio mfg.
            Maybe similar to a Allegro A4408 ???

              Sorry for delay,too much work..here are the photos.cannot make better picture of marking but it looks similar to picture found on aliexpres.Allegro A4408 dont look like mosfet driver,my ic is driving mosfets,there are two double mosfets near this ic.

                clock radio / radio lifespan?
                by shelby5041
                hi
                ive got a modern digital clock radio approx 15yrs old

                my question is how long can a clock radio or a simple radio last ss farcas operating hours?

                since elec components have limited hour lifecspan i would imagine the radio or clock radio would eventually fail.

                the reason i ask is because i have my clock radio on radio function 24/7 for the past 7 years and its still working fine....i leave the radio on ..never turn off past 7years...thats approx 60000 hours

                it uses very little power just a few watts i would imagine that may have something...

                Hello Guys! I have trouble with my car radio Kenwood KDC 3051G I hope someone more knowledgeable can help me, I tried everything in my power that I stumbled upon online.

                My radio is permanently in demo mode, it says Press Volume Knot Cancel Demo and when I press it nothing happens.

                - Tried to unplug radio and plug it back in into power,

                - Tried to reset radio by holding reset button key for 5,10,30 seconds while in power and without power, plugging it back in, it wouldn't work.

                - Tried to hold 3,6 while turning it back on and then pressing 1,2...

                Schematic vs. Reality: Where Are the Resistors on My Sharp Clock Radio? Model FY-70CH
                by TinkerTron
                Hey everyone,

                I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.

                Instead, here's what's been bugging me so far:
                The schematic...

                Sony CFS-5000S radio cassette player no FM reception
                by mikey5791
                Hi forum members,

                In the past i have had many helpful hints from generous forum members in diagnosing and solving issue related to most of my electrical things.

                Fyi, i have been keeping this unit of Sony radio cassette player as the cassette belting has worn off but the radio has been working fine before. Recently, out of a sudden i found out i can't get any radio reception at all (no signal from FM,MW or SW band) except some buzzing warp noise from the speakers.

                I opened the casing inside and checked for any dry solder, burned component or loose wires...
