USB Charger Overvoltage Surge and ESD Protection - TPD1S514

TPD1S514 (ACTIVE)

USB Charger Overvoltage Surge and ESD Protection

 

Description

The TPD1S514 Family consists of single-chip protection solutions for 5-V, 9-V or 12-V USB VBUS lines, 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-V DC. After the EN pin 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 VBUS lines 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.
