Texas Instruments' TPD1S514 is a single-chip protection solution for the USB VBUS line or other power buses. The bidirectional nFET switch ensures safe current flow in both charging and host mode while protecting the internal system circuits from any over voltage condition at the VBUS_CON pin.
On the VBUS_CON pin, this device can handle over voltage protection up to 30 VDC. After the EN pin toggles low, the TPD1S514 waits 20 ms before turning ON the nFET through a soft start delay. TPD1S514 can be factory programmed to multiple VOVP, start up and soft start delay combinations.
