TPS57160-Q1: EN and UVLO information

Srinivasu V

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?

Hi,

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

Thank you,
