LM5060: nPGD min active time

Shunsuke Nagata

Part Number: LM5060

Hi, team,

Is there an Information for minimum low time of nPGD when the device detects failure condition?

I would like to connect nPGD to host MCU. And the MCU checks if the LM5060 is in a fault condition. I would like to ignore short circuit (instantaneous duration). So, I would like to know the minimum time.

Regards,
Nagata.

Hi Nagata,

Let me check on EVM and confirm you.

Hi Nagata-san,

Sorry for the delay. I am on leave and I would be able to get back on this early next week.

Best Regards,

Hi Nagata,

nPGD asserts as soon as the device hits over load current limit and the timer starts counting. As you see in Figure 38 in the datasheet STATUS (nPGD) becomes HIGH immediately for an overload event and timer starts.

Does this answer your question?
