TPD1S514: VBUS_SYS output behaviour during overvoltage protection

Joost DN

Part Number: TPD1S514

Datasheet mentions "Precision clamp circuit limits the Vbus_sys voltage < Vovp"
There are no specifications on this clamping voltage in the datasheet.
Figure 12 show that Vbus_sys shuts off during an overvoltage event.
Is this IC suitable for protecting a device rated up to 5.8V abs max?

Hi,

The team responsible for this device is out of office in observance of Chinese New Year and will be back in a week.

Hello,

Have you referred to Vovp in the datasheet?

Yes, I saw that.
That is the threshold for overvoltage protection on the input. That does not directly specify the output clamping voltage.
Is it designed to clamp or to shut off Vbus_sys?

Hello,

Vbus_power is clamped

Vbus_sys is turned off:
