Hi, team.

When using LMZ31710 in parallel, SLAVE's SENSE pin is open, but does Slave's PWRGD function?

Hello Kobayashi-san,

Good question. Let me double-check with the design team and confirm if the slave PWRGD "functions".

But If current sharing is used, in my opinion the customer should utilize the PWRGD of the master device since its sense+ monitors the output voltage.

Cheers,
Denislav

Hello Kobayashi-san,

I confirmed with the team that the PWRGD of the slave will also be functional.

Cheers,
