Part Number: TPS57160-Q1

I have doubt on EN pin, As it has two functions EN and UVLO. I have calculated the resistors for UVLO and connected to Supply and GND as a voltage divider.

Now, I want to control EN pin with 18 to 36V input. Could you please help on this topic?

Vin - 18.5 to 36V

UVLO : V Start : 18V

             V Stop : 17.2V

EN pin control voltage : 18 to 36V.

Thank you,

  • Hi, 

    do you mean you want the IC to enable when EN voltage is 36V, and want the IC to disable when EN is 18V?

    Thanks & Best Regards

    Hi,

    OV for disable and for enable voltage is between 18 to 36V.
