Key Features
- Wide 2.7 V to 24 V input voltage range covers 5 V, 12 V, and 24 V system rails in a single device
- Adjustable current-limit threshold protects downstream loads from inrush and short-circuit faults with fast response
- Compact 24-pin VQFN with exposed pad enables efficient thermal dissipation on densely populated PCBs
Applications
The TPS259824ONRGET is well suited for hot-swap and load-switch applications in telecom line cards, server power distribution boards, and industrial automation systems. It controls inrush current during board insertion and clamps fault currents, protecting sensitive downstream circuits operating from 12 V or 24 V rails. Its integrated diagnostics and adjustable threshold make it a direct fit for smart power-distribution architectures requiring active current monitoring.

Frequently Asked Questions
What is the maximum input voltage the TPS259824ONRGET can handle, and what supply rails does that cover?
The TPS259824ONRGET supports an input voltage range of 2.7 V to 24 V, covering common system rails such as 3.3 V, 5 V, 12 V, and 24 V. This single-device range reduces the number of SKUs needed in a multi-rail server or telecom chassis design, simplifying BOM management.
How does the adjustable current-limit threshold help protect a 12 V telecom line card during hot-swap insertion?
By setting external resistors to program the current-limit threshold, designers can clamp inrush current to a safe level—typically 2 A to 10 A depending on bulk capacitance—preventing the 12 V bus from drooping more than 200 mV during card insertion into a live backplane, which protects adjacent boards from power disturbances.
What package does the TPS259824ONRGET use, and how many pins does it have?
The device is housed in a 24-pin VQFN package with an exposed thermal pad, measuring approximately 4 mm × 4 mm. The exposed pad improves thermal conductivity to the PCB, enabling power dissipation of over 1 W without an external heatsink when proper copper pours are used on the board.
When is the TPS259824ONRGET a better fit than a discrete MOSFET plus current-sense solution for a 24 V rail?
The TPS259824ONRGET integrates the gate driver, current-sense amplifier, fault timer, and overvoltage comparator in a single 24-pin die, eliminating at least 8 discrete components. For a 24 V industrial I/O card where board area is limited to under 1 cm², this integration reduces component count, lowers assembly cost, and shrinks the power protection block to a footprint smaller than 16 mm².
Which industrial and server applications most benefit from the TPS259824ONRGET fault protection features?
Applications that benefit most include AdvancedTCA and MicroTCA line cards requiring hot-swap compliance on a 12 V or 24 V rail, industrial motor drive control boards with 24 V sensor supplies, and data-center storage enclosures where live board insertion must not disrupt adjacent 48 V-to-12 V power buses. The device's 24 V ceiling and 1-channel eFuse architecture align exactly with these use cases.
