TPD1S514-3YZR Description

Short technical summary and product information.

The Texas Instruments TPD1S514-3YZR is a specialized integrated circuit designed for protecting 5V, 9V, or 12V USB VBUS lines and other power buses. This device provides robust overvoltage protection up to 30V DC with a precision OVP tolerance of less than ±1%. It incorporates surge protection, meeting IEC 61000-4-2 contact discharge standards of ±15 kV and air gap discharge of ±15 kV, as well as IEC 61000-4-5 open circuit voltage of 100V.

The TPD1S514-3YZR features a bidirectional nFET switch that ensures safe current flow in both host and charging modes. It includes a dedicated VBUS_POWER pin for flexible power-up options, even under dead battery conditions. The IC also offers USB inrush current compliance and thermal shutdown (TSD) protection, operating within a temperature range of -40°C to 85°C.

Packaged in a compact 12-DSBGA (YZ) format, this surface-mount IC is suitable for applications requiring reliable USB port protection. Its design ensures that the VBUS_SYS voltage is limited to below the Overvoltage Protection (V OVP) threshold, safeguarding connected systems from voltage transients.
