Hi,

how long VOUT>VIN can trigger Reverse Current Protection?

If there is a pulse VOUT>VIN lasts ns, will it be ignored?

thanks.

Hi Mingmo,

Can you clarify the time duration that the customer is concerned with? You've listed units of nanoseconds, but can you give a more precise value?

Thanks,

- Stephen

Hi Mingmo,

We are looking into this and are considering a transistor level simulation to help answer the question. Please give us 3 business days to work on this and provide a reply.

Thanks,

Hi Mingmo,

Thank you for your patience. We have completed the transistor simulations and the reverse current protection engages after 19 us.

Thanks,
