TPS259802ONRGER

Overview

The TPS259802ONRGER is a single-channel hot-swap controller from Texas Instruments, designed for robust power distribution in industrial and computing systems. It operates within an input voltage range of 2.7V to 24V and supports a maximum output current of 8A. The device integrates an internal N-channel MOSFET with a typical on-resistance of 3mΩ, minimizing conduction losses. Packaged in a 24-VQFN (4x4mm) footprint with an exposed pad for thermal management, it functions as a smart eFuse. Key electrical specifications include a quiescent supply current of 800µA and operation across a junction temperature range of -40°C to 125°C.

Feature Summary

• Integrates programmable circuit breaker functionality with adjustable current limiting and fault timeout parameters.
• Provides comprehensive protection features including overvoltage protection, undervoltage lockout, and latch-off fault modes.
• Supports controlled turn-on slew rate to minimize inrush current during system initialization.
• Features integrated power monitoring capabilities for detecting power failures and managing load conditions.

Applications

• Industrial equipment power distribution modules
• Telecommunications infrastructure power supplies
• Computing server backplane power management
• General-purpose high-current load switching

Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct suffixes for package type and tape/reel configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Cross-reference the manufacturer's datasheet revision history to validate technical specifications against the specific production batch. Ensure compatibility with existing PCB footprints and thermal design constraints before finalizing orders.

Selection Notes

Select this component when a single-channel solution with 8A continuous current capability is required for 24V systems. The 3mΩ on-resistance makes it suitable for applications prioritizing efficiency and low heat dissipation. Consider the programmable nature of the current limit and fault response if system-specific protection thresholds are necessary. The QFN-24 package offers a compact form factor for space-constrained designs requiring surface-mount assembly.
