TL5001: Request review a schematic of TL5001.

David Kim2
Expert 2520 points
Part Number: TL5001
Other Parts Discussed in Thread: SN74LVC2G14, SN74LVC3G14, LMG2100R044

Tool/software:

Hi

My customer configured the circuit with TL5001+SN74LVC3G14+SN74LVC2G14+LMG2100R044.

-SPEC-

Input: DC 5V

Output: DC 60V 5A

It didn't work, so we separated TL5001 and LMG2100R044 and carried out the test.
If I give a PWM signal to LGM2100R044, it works well, but if I connect it to TL5001, it doesn't work.
I think the circuit of TL5001 is wrong, could you please review it?

And I'd like to request a review of the schematic, but they don't want to disclose the schematic.
If you tell me how to send it personally, I will send you a schematic.

Thanks

    Hello David,

    TL5001 has an open collector output transistor, not a pus-pull stage at the output. Please check for a pullup resistor on the output that the signal is able to go high.

    Please request friendship to me in E2E, then we can communicate in the private area.

    Best regards,
    Brigitte

    Hi Birgitte.

    I sent a schematic by private message.

    Thanks

    Hello David,

    Thank you very much for the schematic.

    You mentioned that a PWM signal to the LM2100 works well. What did you drive with the PWM signal? 

    When the TL5001 is used, please measure the Signal 1A on U3.

    Best regards,
    Brigitte

    Hello David,

    As I did not get an answer, I expect that you have been able to solve the issue and will close the thread now. If my assumption is wrong, please post below, or if this thread is locked, please create a new thread.

    Best regards,
    Brigitte
