Manufacturer: Texas Instruments


TPD1S514 datasheet



The TPD1S514 is a single-chip protection solution for the USB V BUS 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 V
BUS_CON pin.

On the V BUS_CON pin, this device can handle over voltage protection up to
30-V DC. 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 V
OVP , start up and soft start delay combinations.


1. Overvoltage Protection at VBUS_CON up to 30-V DC

2. Precision OVP ( < ± 1% Tolerance)

3. Low RON nFET Switch Supports Host and Charging Mode

4. Dedicated VBUS_POWER Pin Offers Flexible Power up Options Under Dead Battery Condition
