LSF0101: Level translator for PECI interface from 1.05V to 1.8V

Sanjeev Ghildiyal1

Part Number: LSF0101
Other Parts Discussed in Thread: TXB0302

I wish to use LSF0101 as Level Translator for Platform Environmental Control Interface (PECI).
Its a single wire, bidirection interface operating up to 1MHz speed.
Level translation required is from 1.05V (PECI HOST) to 1.8V (PECI Client).
Please note that the interface will always have a week pull down on the bus.
Host and device communicate by Pulling up the line. The logic bits are decided based on how long the lines are pulled up.
Please share your comments on this application scenario for LSF0101.

Thanks

Hey Sanjeev,

I see no issues with this.

Hi Dylan

Thanks for your suggestion. I missed to add earlier that our requirement is for auto-bidirectional voltage translator. The AXC family has directional control.

I'm also checking TXB0302 if it meets our voltage level requirements. There are two bits in the device, since we need only one bit, we will leave the other bit unused.

Can you please help with TINA spice models for LSF0101 and TXB0302.

Thanks

Hey Sanjeev,

We don't currently have models for those.
