Key Features
- Wide 4.5 V to 58 V input voltage range with adjustable current limit threshold covers 12 V, 24 V, and 48 V industrial power rails in a single 20-pin HTSSOP package
- Integrated eFUSE with overcurrent, overvoltage, and thermal shutdown protection replaces discrete fuse-and-FET circuits, reducing BOM count and improving response time
- Accurate current-limit adjustment via external resistor enables precise load protection tuning for servers, telecom, and industrial power distribution boards
Applications
The TPS16530PWPR is designed for hot-swap and power sequencing applications in 48 V telecom systems, industrial 24 V equipment, and server power distribution units where robust circuit protection is required. Its wide 4.5 V to 58 V input range and adjustable current limit allow a single device to protect multiple power rail voltages without redesign. The 20-pin HTSSOP package fits standard SMD assembly processes, making it easy to integrate into power management sub-circuits on backplane and motherboards.

Frequently Asked Questions
What input voltage range does the TPS16530PWPR cover, and which industrial bus voltages does it protect?
The TPS16530PWPR operates from 4.5 V to 58 V, making it compatible with 12 V, 24 V, and 48 V industrial and telecom power buses in a single part. This wide input range eliminates the need for separate eFUSE devices for each rail voltage in multi-voltage rack equipment, reducing design complexity and the need to stock multiple SKUs.
How is the current limit threshold adjusted on the TPS16530PWPR, and what protection response time can be expected during an overcurrent event?
The current limit threshold on the TPS16530PWPR is set by an external resistor connected to the ILIM pin, allowing designers to fine-tune trip current for loads from a few hundred milliamps up to the device rated maximum. Upon detecting an overcurrent condition, the eFUSE limits current within microseconds, far faster than a traditional board-mount fuse, protecting downstream load circuits and preventing PCB trace damage in 4.5 V to 58 V distribution systems.
For a 48 V telecom shelf design, what advantage does the TPS16530PWPR offer over a discrete MOSFET plus comparator hot-swap circuit?
The TPS16530PWPR integrates the power FET, current sense, gate driver, and fault logic into a single 20-pin HTSSOP package, replacing at least 5 to 8 discrete components in a conventional 48 V hot-swap circuit. This integration reduces PCB area, eliminates component matching concerns, and provides factory-calibrated overvoltage and thermal shutdown thresholds, shortening design time and improving manufacturing repeatability compared to building equivalent protection from discrete parts.
