The TPD1S414 device is a single-chip solution for a USB connector’s VBUS line protection. The bidirectional nFET switch ensures safe current flow in both charging and host mode while protecting the internal system circuits from any overvoltage conditions at the VBUS_CON pin. On the VBUS_CON pin, this device can handle overvoltage protection up to 30 V. After the EN pin toggles low, the TPD1S414 waits 20 ms before turning ON the nFET through a soft-start delay. ACK pin indicates the FET is completely turned ON.

The typical application interface for the TPD1S414 is the VBUS line in USB connectors. Typical end equipment for TPD1S414 are mobiles phones, tablets, wearables, and electronic-point-of-sale (EPOS). The TPD1S414 can also be applied to any system using an interface with a 5-V power rail.
