TPS259631DDAR

Current Regulation/Management Overview

The TPS259631DDAR is a single-channel hot-swap voltage controller and electronic fuse from Texas Instruments, housed in an 8-SO PowerPad package. It operates within a supply voltage range of 2.7 V to 19 V with a typical on-resistance of 85 mΩ. The device supports adjustable current limits ranging from 0.13 A to 2 A, featuring a maximum current limit accuracy of ±10.4% across the full range and ±5.5% at the 1-A setting. It includes an active-high enable input with adjustable undervoltage lockout.

Current Regulation/Management Feature Summary

• Provides accurate current regulation and management for load protection
• Integrates fast overvoltage protection mechanisms
• Features an accurate current monitor for system feedback

Current Regulation/Management Applications

• Hot-swap voltage control in server backplanes
• Load protection in industrial equipment power distribution
• Electronic fuse implementation in communication infrastructure

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DDAR' corresponds to the 8-SO PowerPad package and tape-and-reel shipping configuration. Confirm that the component meets the required operating temperature range of -40°C to +125°C for your specific application environment. Ensure compatibility with the 2.7-V to 19-V input voltage window during system design validation.

Current Regulation/Management Selection Notes

Select this part when a single-channel solution with up to 2-A current capability is required. The 85-mΩ on-resistance makes it suitable for applications prioritizing low conduction loss. Choose this model if precise current limiting with ±10.4% accuracy is necessary for protecting sensitive downstream loads without excessive voltage drop.

Current Regulation/Management Part Context

This component belongs to the TPS2596 family of integrated hot-swap controllers. These devices are designed to manage power insertion into live systems, preventing inrush currents and short circuits. The TPS2596 series offers various current ratings and package options to suit different power density requirements in modern electronic systems.

Current Regulation/Management Replacement Considerations

The TPS259620DDAR is a verified substitute within the same family, offering similar functionality with potentially different current limit settings. Verify pin-to-pin compatibility and ensure the replacement meets the specific electrical requirements of the target circuit.
