Key Features
- Ultra-low 10 mΩ on-resistance minimizing conduction losses for 7 A load currents in 2.7 V to 23 V power rails
- Fast overvoltage and overcurrent protection with adjustable threshold protecting sensitive downstream ICs in industrial and automotive 12 V systems
- 8 A peak output current capability handling inrush and transient loads without nuisance trips in motor and solenoid drive applications
- Compact 10-pin LCC package with integrated MOSFET enabling single-chip hot-plug and fault management replacing discrete protection circuits
Applications
PTPS25972ARPWR is designed for hot-plug and power sequencing applications in industrial equipment, server boards, and telecom systems operating from 5 V, 12 V, or up to 23 V rails where downstream load protection is critical. Its fast overvoltage and overcurrent detection prevents damage to sensitive ICs during input transients or short-circuit events, making it suitable for motor drive power stages and field-installed module protection. The adjustable threshold and 7 A continuous current handling also make it a practical eFuse choice in battery-powered tools and 24 V industrial bus designs requiring precise load management.

Frequently Asked Questions
What input voltage range and maximum continuous current does PTPS25972ARPWR support?
PTPS25972ARPWR operates from 2.7 V to 23 V input and supports up to 7 A continuous output current with an 8 A peak rating. This wide voltage range covers 3.3 V, 5 V, 12 V, and 24 V nominal supply rails, making it a single-part protection solution across many industrial and server power architectures without needing separate eFuse ICs per rail.
How does the 10 mΩ on-resistance of PTPS25972ARPWR affect power loss at full 7 A load?
At 7 A continuous load, the 10 mΩ on-resistance dissipates approximately 490 mW (I² x R = 49 x 0.010), which is low enough to avoid significant thermal derating in a compact 10-pin LCC package with moderate PCB copper pours. This compares favorably with discrete protection MOSFETs and fuses that typically add 50 mΩ or more to the power path at similar current ratings.
Which industrial or server designs benefit from PTPS25972ARPWR's adjustable overvoltage threshold on a 12 V rail?
Server power distribution boards and industrial field I/O modules on a 12 V rail benefit most because the adjustable threshold allows fine-tuning the trip point to 13 V or 14 V rather than a fixed factory value. This prevents nuisance tripping from normal 12 V rail transients of plus or minus 10% while still protecting downstream ICs rated to 15 V maximum against genuine overvoltage faults of 5 ms or longer.
When is PTPS25972ARPWR a better choice than a traditional polyfuse for 7 A board-level protection?
PTPS25972ARPWR is preferred over a polyfuse when fast response time, precise adjustable trip thresholds, and automatic restart after fault clearance are required at 7 A and up to 23 V. Polyfuses respond in seconds and have trip currents that drift with temperature, while the eFuse reacts in microseconds and maintains consistent 10 mΩ on-resistance across the full operating temperature range, delivering deterministic protection for sensitive 12 V or 5 V load circuits.
