TPS25210ARPWR

Current Regulation/Management Overview

The TPS25210ARPWR is a hot-swap voltage controller and eFuse from Texas Instruments, designed for 2.7-V to 5.7-V input ranges with a 28-V absolute maximum rating. It integrates back-to-back FETs providing a low on-resistance of 31-mΩ and supports up to 4-A output current. The device withstands negative voltages up to –15 V and operates within a temperature range of -40°C to +125°C. Packaged in a 10-VQFN-HR (2x2) surface-mount format, it offers precise fault reporting and reverse polarity protection.

Current Regulation/Management Feature Summary

• Integrated back-to-back FETs with low on-resistance
• Precise fault reporting for effective system troubleshooting
• Reverse polarity protection capability

Current Regulation/Management Applications

• Hot-swap voltage control
• System power distribution
• eFuse implementation

Current Regulation/Management Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure compatibility with required thermal and electrical specifications. Confirm that the 10-VQFN-HR package variant matches the intended PCB layout constraints. Cross-reference the datasheet revision history to validate parameter consistency before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when an integrated solution for overcurrent protection and hot-swap functionality is required within a 2.7-V to 5.7-V operating window. The low on-resistance minimizes power loss during normal operation, while the compact QFN package suits space-constrained designs requiring robust fault reporting capabilities.

Current Regulation/Management Part Context

This part belongs to the TPS2521xx series of eFuses, which are engineered to provide comprehensive protection for downstream loads. The series integrates high-side switching with advanced monitoring features, serving as a reliable alternative to discrete MOSFET-based protection circuits in modern electronic systems.

Current Regulation/Management Replacement Considerations

Consult the official TI cross-reference guide for verified substitutes. Ensure any replacement maintains the 10-VQFN-HR footprint and compatible electrical ratings.
