TPS259481LYWPR

Current Regulation/Management Overview

The TPS259481LYWPR is a single-channel hot-swap voltage controller and eFuse from Texas Instruments, designed for robust power distribution. It supports an operating input voltage range of 3.5 V to 23 V, with a maximum absolute rating of 28 V. The device integrates back-to-back N-channel MOSFETs with a typical on-resistance of 12.2 mΩ, enabling continuous current handling up to 8 A. It operates within a temperature range of -40°C to +125°C and is housed in a DSBGA-12 package.

Current Regulation/Management Feature Summary

• Integrates back-to-back FETs for bidirectional current flow and reverse polarity protection
• Supports powering from either the input (IN) or output (OUT) pin
• Provides precise current limiting and thermal shutdown protection

Current Regulation/Management Applications

• Hot-swap insertion in server and storage backplanes
• Power distribution units (PDUs) and industrial control systems
• Telecommunications equipment requiring redundant power inputs

Current Regulation/Management Procurement Notes

Verify the specific suffix 'LYWPR' against the manufacturer's latest datasheet to confirm package type and marking. Ensure compatibility with system voltage levels between 3.5 V and 23 V. Check for recent Product Change Notifications (PCN) regarding manufacturing site or material changes. Confirm lead times as they may vary based on production cycles.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with low on-resistance and high current capacity is required. It is suitable for applications needing bidirectional power flow and flexible power sourcing from either input or output. Compare against other TPS2594x variants if different current ratings or voltage ranges are needed.

Current Regulation/Management Part Context

This part belongs to the TPS25948xx family of eFuses, which are designed for high-reliability power management. The family offers various current ratings and on-resistances to suit different load requirements while maintaining a compact footprint. These devices are commonly used in environments demanding strict protection against overcurrent and short circuits.

Current Regulation/Management Replacement Considerations

Direct substitutes include TPS259480LYWPR and TPS259482LYWPR from the same series, offering similar features with potentially different current ratings. Verify pinout compatibility and electrical specifications before substitution.
