TPS259631DDAT

Current Regulation/Management Overview

The TPS259631DDAT is a hot-swap voltage controller and electronic fuse from Texas Instruments, designed for input voltages ranging from 2.7 V to 19 V. It supports output currents between 0.13 A and 2 A with a typical on-resistance of 85 mΩ. The device features an active-high enable input and adjustable undervoltage lockout. Packaged in an 8-pin HSOP with a power pad, it operates within a temperature range of -40°C to 125°C. This component integrates precise current regulation and protection mechanisms suitable for high-reliability applications.

Current Regulation/Management Feature Summary

• Integrates accurate current regulation and protection functions within a compact package
• Supports wide input voltage ranges for flexible system design
• Features low on-resistance to minimize power loss during operation

Current Regulation/Management Applications

• Hot-swap controller implementations
• Electronic fuse circuits
• Voltage regulator systems requiring overcurrent protection

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DDAT' corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the 8-pin HSOP power pad footprint matches your PCB layout guidelines. Ensure compatibility with the specified 2.7-V to 19-V input range for your target application voltage levels before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when a robust electronic fuse solution is needed for inputs up to 19 V. Consider the 85-mΩ typical on-resistance for efficiency requirements. Verify that the 0.13-A to 2-A current range aligns with load specifications. The active-high enable input simplifies control logic integration compared to other enable configurations.

Current Regulation/Management Part Context

This part belongs to the TPS2596 family of eFuses, which are designed for high-side switching and protection. The TPS259631DDAT specifically offers a fixed current limit setting within the broader family capabilities. It serves as a replacement for discrete MOSFET-based solutions, providing integrated thermal and electrical protection in a single IC form factor.

Current Regulation/Management Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the TPS2596 series if different current limits or package options are required. Verify that any substitute maintains the same 8-pin HSOP power pad outline and electrical characteristics to ensure board compatibility without redesign.
