  • LED Driver chip info needed

    I have a board from some medical equipment that has seven multi-section LEDs that I want to use on an amp for novelty but I cannot find a datasheet for the driver IC anywhere. I've looked for hours, maybe just not in the right places? It's a TSCC51DBP-12CA as shown in the picture. Any ideas? The only place I can find where this is even mentioned is to get a quote on production numbers.

    If I were to hazard a guess, I'd say it was a mask programmed micro controller, maybe 8051 series. If it's dead you are out of luck unless you have the capability and time to engineer a replacement.
    Experience is something you get, just after you really needed it.

      Something Intel made circa 1980, from the copyright stamp, unless the 80 82 following the word "Intel" is actually a catalog number of sorts.

      edit: after looking over wikipedia, it might be likely this is something in the 8080 family, as mentioned above.

        I think it's a Temic (formerly Telefunken) ASIC using an Intel core.
        If so there will be no replacement or documentation available.

          I was afraid of that.

            Your moniker "gui_tarzan" suggets that you might a a coder of user interfaces. If that is true you will have little difficulty using something like an Aruduino board to light up those displays. Just search for "Arduino 7 segment code".

              Actually it goes back to 1995 when I first got on the Internet. I was going to chat rooms as "Spidey", a reference to Spiderman, where people would say things like "Robert walks into the room with a hangover from last night" and so on. I used the "Spidey swings into the room on a web" until someone took my handle and was saying inappropriate things pretending to be me. So I changed it to Gui_tarzan who "entered room swinging from a guitar cord" thing. After a while people started calling me "GT" so that became my handle until the site closed down a few years later. Gui_tarzan is actually a play on "Gitarzan" by Ray Stevens' song from the late 60s.

              I hate coding with a passion. I know enough to know just how much I hate it. The last thing I want to do is try to learn yet another language.

                  When I die I want to go quietly in my sleep like my grandpa did. Not kicking and screaming like the passengers in his car.

                      Not my area, hate digital things, but you won´t find them as "seven multi-section LEDs" , search for "intel 7 segment display drivers".

                        If it's a tube amp you want to use nixie tubes anyway.
                        "Everything is better with a tube. I have a customer with an all-tube pacemaker. His heartbeat is steady, reassuring and dependable, not like a modern heartbeat. And if it goes wrong he can fix it himself. You can't do that with SMD." - Mick Bailey

                            Of course. I drew a blank on the name earlier.

                              I think the chip was manufactured by Temic.
