Overview
The TPS259807ONRGER is a single-channel hot-swap voltage controller from Texas Instruments, functioning as a smart eFuse. It operates within an input voltage range of 2.7 V to 24 V and supports a continuous current limit of 8 A. The device features a low on-resistance of 3 mΩ and is housed in a 24-pin QFN package (4x4 mm). It includes power fail detection and is rated for operation between -40°C and +125°C.
Feature Summary
- Integrates an internal N-channel MOSFET with programmable current limiting for precise load protection.
- Provides accurate load current monitoring via a dedicated monitor pin for system feedback.
- Includes adjustable transient fault management to handle inrush currents and short circuits effectively.
Applications
- PCI/PCIe backplane systems requiring hot-swap capabilities
- Industrial equipment power distribution modules
- Telecommunications infrastructure power inputs
Procurement Notes
Verify the complete part number including suffixes such as 'ONRGER' to ensure correct packaging and temperature grade. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference datasheet revisions to validate electrical specifications against current production versions.
Selection Notes
Select this component when an 8 A current rating and 24 V maximum input are required. Ensure the 3 mΩ on-resistance meets thermal dissipation requirements for the specific PCB layout. Verify that the 24-VQFN package dimensions fit the available footprint constraints.
Part Context
This device belongs to the TPS25980 family of smart eFuses designed for high-reliability applications. It offers integrated protection features typically found in discrete solutions, reducing bill-of-materials count. The family provides various current ratings and resistance options to suit different power distribution needs.
Replacement Considerations
Consult the TPS25980 series datasheet for compatible alternatives with similar current ratings or package types. Verify pin-to-pin compatibility before substituting with other members of the TPS25980 family.
