LM5176: How to reach maximum hysteresis?

Andrey Yakimov

Part Number: LM5176

Hi, Team,

The hysteresis between the UVLO turn-on threshold and turn-off threshold is set by the upper resistor in the

EN/UVLO resistor divider.

I need maximum hysteresis in my system.

What is the maximum value of the upper resistor?

Regards, Andrey.

Hi Andrey,

It is possible to put a resistor is series with the UVLO pin to help set the hysteresis as needed. Please see the drawing below.

Hi Garrett,
It really works. And it isn't necessary to put resistors of large values.
Best regards, Andrey
