TPS259250DRCT

Current Regulation/Management Overview

The TPS259250DRCT is a Texas Instruments hot-swap voltage controller and eFuse IC housed in a VSON-10 package. It supports an input supply voltage range from 4.5V to 18V with a maximum continuous output current of 5A. The device features a low on-resistance of 30mΩ and includes adjustable current limiting with ±15% accuracy. Quiescent current is specified at 420µA, and it operates within a temperature range of -40°C to +85°C.

Current Regulation/Management Feature Summary

• Integrated power path management with adjustable current limit for precise load protection
• Built-in reverse current blocking capability to prevent backflow during system shutdown
• Configurable soft-start timing to manage inrush currents during power-up sequences

Current Regulation/Management Applications

• Hot-pluggable peripheral interface circuits requiring robust power distribution
• Industrial control systems needing isolated or protected power rails
• Telecommunications equipment utilizing standard voltage levels for module insertion

Current Regulation/Management Procurement Notes

Verify the specific suffix DRCT corresponds to the cut-tape packaging format required for your assembly line. Confirm that the 30mΩ on-resistance and 5A current rating align with your thermal design constraints. Ensure the VSON-10 footprint matches your PCB layout guidelines before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when designing systems that require integrated eFuse functionality without external MOSFETs. It is suitable for applications demanding high accuracy in current limiting and reverse current protection. Consider the 420µA quiescent current impact on overall system efficiency during standby modes compared to lower-power alternatives.

Current Regulation/Management Part Context

This part belongs to the TPS2592x family of hot-swap controllers from Texas Instruments. These devices are designed to replace discrete solutions involving separate MOSFETs and control logic. The family offers various current ratings and voltage ranges to accommodate different power distribution requirements in compact form factors.

Current Regulation/Management Replacement Considerations

The TPS259251DRCT is a documented alternative within the same series. Verify if the specific pinout or feature set differences between the 50 and 51 variants meet your design requirements before substituting.
