TPS65310A-Q1: TPS65310A-Q1 Acceptable VIO Voltages

Brett Kutscher

Part Number: TPS65310A-Q1

Can I run VIO at 2.5V? Will this cause the SPI to be 2.5V compatible?

V_VIOMON_TH looks like it trips at 3.13V, but there is note under the V_RESL electrical conditions that has VIO at 1.2V, so I figured I would double check.

Anecdotally, can it be run at 5V?

Thank you,

Hi,

Could you please provide me the details about this project and customer?

Minimum voltage on VIO should be more than 3.13V and it should survive 5V input voltage.

VIO=1.2V mentioned in the datasheet is for test condition for testing V_RESL only ( just to have non zero low voltage) and this is nothing to do with VIO threshold.

regards,

Murthy
