TPS259630DDAT

Current Regulation/Management Overview

The TPS259630DDAT is a hot-swap voltage controller and eFuse from the Texas Instruments TPS2596 family. It operates within an input voltage range of 2.7 V to 19 V and supports adjustable current limiting from 0.13 A to 2 A. The device features a typical on-resistance (Ron) of 85 mΩ. It includes an active-high enable input with adjustable undervoltage lockout (UVLO). The component is housed in an SO-PowerPad-8 package and is designed for surface-mount installation.

Current Regulation/Management Feature Summary

• Integrated electronic fuse functionality with adjustable current limit protection
• Low on-resistance for efficient power delivery and minimal voltage drop
• Adjustable undervoltage lockout thresholds for flexible system startup control
• Active-high enable input for simple logic-level interface

Current Regulation/Management Applications

• Hot-swap insertion protection for backplane systems
• Power distribution units requiring precise current monitoring
• Server and storage enclosure power management
• Industrial equipment input stage protection

Current Regulation/Management Procurement Notes

Verify the specific suffix DDAT against the manufacturer's official datasheet to confirm tape-and-reel packaging and pin configuration. Ensure the selected variant matches the required current limit adjustment resistor values. Cross-reference the RoHS compliance status and moisture sensitivity level with the latest production data before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when a wide input voltage range up to 19 V is required alongside high-current handling capabilities. The adjustable UVLO feature allows customization of turn-on thresholds to prevent inrush issues. Compare the 85 mΩ on-resistance against thermal dissipation requirements in the target application environment to ensure adequate heat sinking or PCB copper area allocation.

Current Regulation/Management Part Context

This part belongs to the TPS2596 series of integrated eFuses, which are designed for robust power path management. The series offers various current limit ranges and package options to suit different power density needs. The TPS259630DDAT specifically targets applications needing higher current capacity compared to lower-end variants in the same family.

Current Regulation/Management Replacement Considerations

Direct substitutes include other parts within the TPS2596 family such as the TPS259620 or TPS259640, provided their current limits and pinouts are compatible. Verify that any replacement maintains the same SO-PowerPad-8 footprint and electrical characteristics to avoid redesigning the PCB layout.
