TPS3710: Start-up delay

K.Yaita

Part Number: TPS3710

Hi Team,

The datasheet shows
>(2) During power on, VDD must exceed 1.8 V for at least 150 µs before the output is in a correct state.

I believe "1.8V" is typo and 0.8V is correct because V(POR) is 0.8V(max).
Is my understanding correct?

Best Regards,
Yaita

Hello Yaita,

1.8V is the minimum supply voltage level for this device. The footnote is correct. Thanks.

Hi Masoud-san,

Thank you for your reply.
I want to clarify about td(start).
Is the following V(POR) typo and 1.8V is correct?

Best Regards,

Hi Yaita,

Sorry for the delay, the Td start does begin at Vdd min, the typo on the timing diagram should be fix on the next revision.

Thank you,

Jesse
