Part Number: TPS25840-Q1

Hi team,

Customer want to know the behavior of VBUS(DCDC switching) and LS_GD under "Overvoltage on the data lines" fault.

It's not clear on the datasheet. Please give me your advice.

Hi Hirai,

When overvoltage occurs on the data lines(DP/DM), LS_GD still high and DCDC still switching. In this situation, fault goes low and data switch will shutdown.

Best Regards,
