TPS25983: Can I connect 1.8V Pull up to the Power GOOD signal and directly connect to FPGA?

Anush Balraj1

Part Number: TPS25983

Tool/software:

Iam using an FPGA with IO voltage 1.8V. So please can anybody confirm if I can connect 1.8V pull up on the PG signal and directly connect to FPGA. So I can avoid using level translator.

The datasheet refers 3.3V pull up. So please confirm.

Hi Arush,

Thanks for the reply.

It is shown in the typical application circuit.
So i just wanted to confirm if I can use 1.8V to connect directly to the FPGA.

Hi Anush,

Yes, it is fine if you pull it up with 1.8V. This is just an example. Internally PG pin is open drain pin.

Please click resolved to close the thread.
