TLV62585: Power good output just after POR

Shunsuke Nagata

Part Number: TLV62585

Hi,

Could you please let me know the output condition of PG just after POR?

Just after POR and not rump up to VDD = 0.4V, The device may not run. In this case, will PG output keep LOW? or should it be open?

Regards,
Nagata.

Hi Nagata-san,

The PG status with respect to VIN level is indicated in the table below. Does it answer your queries?

Best regards,

Excel -san,

Thank you for your support. I understand PG out is High-Z state under UVLO. I would like to know Vout condition in under UVLO in this time. Is is possible to keep 0V in all of voltage under UVLO? Or should it be High-Z when the input voltage is <0.4V?

Regards,
Nagata.
