TPS259827LNRGER

Current Regulation/Management Overview

The TPS259827LNRGER is a single-channel hot-swap voltage controller from Texas Instruments, functioning as an eFuse with a typical on-resistance of 2.7 milliohms and a maximum continuous current rating of 15 amperes. It operates within an input voltage range of 2.7 volts to 24 volts and supports adjustable current limiting between 2 amperes and 15 amperes. The device features accurate load current monitoring and adjustable transient fault management capabilities. It is housed in a VQFN-24 package and is rated for operation across a temperature range of -40 degrees Celsius to +125 degrees Celsius.

Current Regulation/Management Feature Summary

• Integrates accurate load current monitoring for precise power delivery management
• Provides adjustable transient fault management to handle dynamic load conditions
• Features low on-resistance to minimize conduction losses during normal operation

Current Regulation/Management Applications

• Server and storage backplane protection
• Industrial control system power distribution
• Telecommunications infrastructure equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix LNRGER against the official datasheet to confirm the reel packaging configuration. Ensure compatibility with the target board's thermal design requirements given the VQFN-24 package. Confirm that the application voltage remains within the specified 2.7V to 24V operational window. Validate that the required current limit settings align with the device's adjustable range specifications.

Current Regulation/Management Selection Notes

Select this component when high-side switching with integrated protection is required for 24V systems. The 15A capacity suits applications needing robust overcurrent handling. The adjustable current limit allows customization for different load profiles. Consider the VQFN-24 footprint for PCB layout constraints. Verify thermal dissipation needs based on the 2.7mΩ on-resistance under expected load conditions.

Current Regulation/Management Part Context

This part belongs to the TPS25982x series of smart eFuses designed for high-current, high-voltage applications. It complements other variants like the TPS259823 and TPS259824 by offering specific current and resistance characteristics. The series focuses on providing comprehensive protection features including short-circuit and overload protection in a compact form factor suitable for dense PCB layouts.

Current Regulation/Management Replacement Considerations

Direct substitutes include TPS259823LNRGET and TPS259824ONRGET. Verify pinout compatibility and electrical parameter alignment before substitution. Check if alternative packages meet the thermal and spatial requirements of the existing design.
