Hi Hale Tan

what do you mean by 3.3V I2C

TPSM8S6C24 module uses TPS546D24S IC and only support PMBus

Thank you

Savith,

Sorry about the mistake. Just want to make sure, whether TPSM8S6C24 can support 3.3V level voltage? Because the customers use GPIO in the MCU is 3.3V and they want to make sure whether need level shifter to change the voltage. I see that it can support. So just want to get confirmation.

Hi Hale

The CLK & DATA pins require pull up from 1.8 to 5.5V. Alternatively, the device uses the electrical specifications from PMBUS 1.3.

I would say 3.3V is okay

Thank you

Savith
