TPS259630DDAR

Current Regulation/Management Overview

The TPS259630DDAR is a hot-swap voltage controller and eFuse from Texas Instruments, designed for single-channel power distribution. It operates within an input voltage range of 2.7 V to 19 V and supports load currents from 0.13 A to 2 A. The device features a typical on-resistance (Ron) of 85 mΩ. Key technical specifications include an active high enable input with adjustable undervoltage lockout (UVLO), accurate current monitoring capabilities, and fast overvoltage protection. The component is housed in an SO-PowerPad-8 surface-mount package and is rated for operation between -40°C and +125°C.

Current Regulation/Management Feature Summary

• Integrates hot-swap control and eFuse functionality for robust power path management
• Provides accurate current monitoring for precise load sensing and protection
• Features fast overvoltage protection to safeguard downstream circuitry
• Includes adjustable undervoltage lockout via the active high enable input

Current Regulation/Management Applications

• Server and storage backplane power distribution
• Industrial equipment input power protection
• Telecommunications infrastructure power systems
• Point-of-load (POL) module input stages

Current Regulation/Management Procurement Notes

Verify the specific suffix '30' against the official Texas Instruments datasheet to confirm the exact current limit threshold and UVLO settings, as these parameters vary across the TPS2596 family. Ensure the SO-PowerPad-8 thermal pad connection requirements are met during PCB layout to maintain specified performance and reliability standards under maximum load conditions.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution is required for voltages up to 19 V with peak currents reaching 2 A. The low on-resistance minimizes conduction losses, while the integrated monitoring simplifies system design by reducing external component count. Consider the thermal dissipation capabilities of the SO-PowerPad-8 package relative to the expected ambient temperature and duty cycle.

Current Regulation/Management Part Context

This part belongs to the TPS2596 family of integrated eFuses and hot-swap controllers. These devices are engineered to replace discrete MOSFETs and protection circuits, offering a compact footprint and enhanced reliability. The family provides various configurations tailored for different current ratings and protection thresholds, serving as critical components in modern electronic power distribution networks.

Current Regulation/Management Replacement Considerations

Consult the Texas Instruments TPS2596 family cross-reference for compatible alternatives such as the TPS259620 or TPS259640 series. Verify that substitute parts match the required input voltage range, current handling capacity, and pinout compatibility before implementation.
