SN6501: Transformer Driver SN6501: Second Source available ?

Part Number: SN6501
Other Parts Discussed in Thread: SN6505B, SN6505A

Hi


Is there a second source available for the transformer driver SN6501?

(if not a SOT-23, could anyone recommend a part in an other package?)


Thanks,

Michael

    Hi Michael,

    My apologies, I couldn't get your question right. Can you please briefly explain on what you are looking at?
    Apart from SN6501, we have SN6505A and SN6505B isolated transformer drivers.

    Hi Tejas

    Thank you for your answer.

    In other words (my mother tongue is German):

    If TI decides to stop producing the transformer driver SN6501, I would have a problem. Therefore, I was looking for an alternative transformer driver from an other manufacturer in the same package (SOT-23) but I couldn't find one. There is a similar IC from Maxim Integrated: MAX253. But this is a SOIC-8 or a uMax-8 Package.

    Regards,
    Simon

    Hi Tejas

    Regarding your suggestion SN6505:
    I guess, SN6505 would be possible as well. However, it's a 6-Pin SOT-23 Package, but the the Pin 1 -Pin4 are the same. This might be a possibility.

    Hi Simon,

    You can design the system considering SN6505 transformer driver with no external clock configuration (pulling pin 6 of SN6505 to GND). This way your system will be compatible for both SN6505 as well as SN6501.

    Also, you can confidently use TI products and not worry about obsolescence as , TI’s Product withdrawal/discontinuance process complies with JESD48, latest issue. TI makes an effort to not obsolete products out of convenience. Convenience means: low running device, poor yields, limited customer adoption or similar items. TI’s obsolescence withdrawal schedule provides a longer lead time than the industry standard. TI allows 12 months for the last order and an additional 6 months to take final delivery of obsolete items. In rare circumstances, an accelerated withdrawal schedule may be necessary. In such cases, TI will communicate the last buy and final delivery dates in the EOL notice, along with an explanation of the circumstances necessitating the early withdrawal.
