TPS259830ONRGER

Overview

The TPS259830ONRGER is a single-channel hot-swap voltage controller manufactured by Texas Instruments. It supports an input voltage range of 2.7 V to 26 V and delivers a maximum continuous current of 18 A. The device features an internal switch with an on-resistance of 2.7 mΩ. It is housed in a 24-VQFN (4x4 mm) package with an exposed thermal pad, designed for surface-mount installation. The component operates within a temperature range of -40°C to +125°C TJ.

Feature Summary

• Integrates a high-current power switch with low on-resistance for efficient power delivery.
• Provides comprehensive circuit protection including overvoltage, undervoltage, and current limiting.
• Supports programmable soft-start and fault management for controlled power sequencing.

Applications

• PCI bus power distribution
• Industrial backplane systems
• Telecommunications infrastructure

Procurement Notes

Verify the complete part number against official Texas Instruments documentation to ensure correct suffix alignment. Confirm that the specific ordering code matches the required package variant and tape-and-reel specifications. Cross-reference the manufacturer's latest datasheet revision to validate all electrical parameters before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring robust hot-swap capabilities for high-current loads up to 18 A. Ensure the application environment stays within the specified operating temperature range. Verify that the PCB layout accommodates the 24-VQFN package dimensions and provides adequate thermal dissipation through the exposed pad for optimal performance.

Part Context

This device belongs to the TPS25980 family of smart eFuses and hot-swap controllers from Texas Instruments. The family offers integrated solutions for power distribution and protection in demanding industrial and communication applications. These components replace traditional discrete fuses and relay-based switching circuits, providing compact and reliable power management.

Replacement Considerations

Consult the official TPS25980/TPS25983/TPS25982 datasheet for potential pin-compatible or functionally similar alternatives within the same product family. Verify that any substitute component meets the specific voltage and current requirements of the target application.
