Part Number: TPS54540

Tool/software:

Hi, For the IC TPS54540DDAR can we supply more than 8.4V to the ENABLE PIN to set "Under Voltage Lockout"? if so what is the maximum voltage we can supply.

in datasheet it is mentioned that when we exceed more than 8.4V IC has got internal zener diode to clamp to 5.8V and Please go through below image.

Thanks.

    Hello Venkatesh

    Thanks for writing to us!

    The absolute maximum rating of EN pin is 8.4 V. However, you can apply higher voltages to EN pin through resistor divider just make sure current sunk by EN pin is below 150 uA.

    I hope this answers you question. Let me know if need further clarification.

    Thank you

    Regards
