TPD3S044DBVR Description

Short technical summary and product information.

The Texas Instruments TPD3S044DBVR is an active component designed for USB host port protection. It integrates current limiting and electrostatic discharge (ESD) protection for both D+ and D– data lines.

 

This device supports USB 2.0 and USB 3.0 interfaces, featuring a current limit rating of 1.5A and a typical dynamic resistance of 0.2 Ω. It offers robust ESD protection, rated at ±12-kV contact discharge and ±15-kV air gap discharge according to IEC 61000-4-2 standards. The clamping voltage is 10V, with a typical IO capacitance of 1.4 pF.

 

Packaged in a compact SOT-23-6 surface-mount form factor, the TPD3S044DBVR operates within an ambient temperature range of -40°C to 85°C. Its features include fast overcurrent response (2 μs), integrated output discharge, reverse current blocking, short-circuit protection, and over-temperature protection with auto-restart.

 

This IC is suitable for applications requiring reliable USB port protection against overcurrent and ESD events, ensuring the integrity of connected devices and the host system.
