LM5069: Response time during OV & UV event

Hi Brian,

Thanks for reaching out!. Can you share more information about this project use case.

1A) The typical response time for OV and UV events is 11us.

2A) No, timer is not active during OV and UV events. The GATE will be pulled down once the OVP or UVP threshold is reached

Let me know if you have more questions.

Best Regards,
Rakesh

What's the design consideration of the detection time 11uS for OV and UV?

Hi Brian,

Do you mean the minimum required time, Vin to be higher than OV or UV thresholds for detection ?

Is there any reason 11uS for response time when the OV and UV events from design's point of view?

Regards,

Brian

Why customer asking this question is because the duration time for surge test is 8uS around. When doing surge test, the device would be turned off with 11uS detection time of LM5069.

Why the detection time of LM5069 is 11uS only? Could it be longer to ms Level?

Brian

Hi Brian,

Please add capacitor at OVLO pin  to increase delay.
