TPD3S044DBVR

Current Regulation/Management Overview

The TPD3S044DBVR is a high-side current-limit switch manufactured by Texas Instruments, designed for portable applications. It operates within an input voltage range of 4.5V to 5.5V and delivers a maximum output current of 500mA. The device features a low on-resistance (RdsOn) of 106mΩ and includes integrated ESD protection rated at ±15kV HBM. Packaged in a compact SOT-23-6 surface-mount case measuring 3.05mm x 1.75mm x 1.3mm, it supports an operating temperature range from -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrates high-side power switching with fixed current limiting capability
• Provides robust electrostatic discharge protection on data lines
• Utilizes a compact surface-mount package for space-constrained designs

Current Regulation/Management Applications

• Portable electronic devices requiring USB port protection
• Battery-powered systems needing overcurrent safeguarding
• Consumer electronics with external peripheral interfaces

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DBVR' confirms the SOT-23-6 tape-and-reel packaging configuration. Ensure the application environment remains within the specified -40°C to +85°C operational temperature limits. Confirm that the 500mA current limit aligns with the downstream load requirements to prevent unintended tripping during normal operation.

Current Regulation/Management Selection Notes

Select this component when a single-channel high-side switch with integrated ESD protection is required for 5V logic systems. Compare against the TPD3S014 variant if a different current threshold or pinout compatibility is needed. Verify that the 106mΩ on-resistance meets the system's voltage drop and power dissipation constraints under full load conditions.

Current Regulation/Management Part Context

This part belongs to the TPD3S series of current-limit switches from Texas Instruments. These components are engineered specifically for protecting USB ports and other sensitive data lines in mobile and handheld devices. The series combines power management functions with signal integrity protection in a minimal footprint.

Current Regulation/Management Replacement Considerations

The TPD3S014DBVR is a functional alternative within the same family, offering similar high-side switching capabilities.
