Dear team,
May I double confirm with you the IOL(PMBUS) spec in datasheet. It show the minimum value is 4 mA.
Does that mean driver low capability is higher than 4mA?
The reason why we need to confirm this spec is we have 6pcs TPS546C23 on our board, and need PMBUS control.
We need to calculate the pull high resistors value.
Currently, we design one pull high resister 4.7K-ohm to 3.3V level for SMBUS_Alert. And one pull high resister 1K-ohm to 3.3V level for PMB_DATA.
What is the minimum and maximum pull up resistor for the two BUS?
Regards,
Ben
