LM43603: PGOOD pin connection

Shoo Saga

Part Number: LM43603

Hi teams,

My customer want to pull up PGOOD pin to VCC pin.

Is that OK?

Regarding to the datasheet, It doesn't allow VCC pin to connect any load.

Thanks,

Shoo

Hello

Yes, it is OK to use the VCC for a logic pull-up for the PGOOD.

You can use any value resistor between 10k and 100k.

The VCC should not be used to supply a heavy load.

Thanks
