The TPD1S514 Family consists of single-chip protection solutions for 5-V, 9-V or 12-V USB VBUSlines, 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_CONpin. On the VBUS_CONpin, this device can handle over voltage protection up to 30-V DC. After theENpin toggles low, any device in the TPD1S514 Family waits 20 ms before turning ON the nFET through a soft start delay.
Typical application interfaces for the TPD1S514 Family are VBUSlines in USB connectors typically found in cell phones, tablets, eBooks, and portable media players. The TPD1S514 Family can also be applied to any system using an interface for a 5-V, 9-V, or 12-V power rail.
