NPS3102A - 12V eFuse

Description

NPS3102A and NPS3102B are low-ohmic (17 mΩ), high current (13.5 A), resettable electronic fuses that are targeted for 12 V applications.

They are designed to protect downstream loads from exposure to excessive voltage and protect the power supply from load faults and large inrush currents.

Features

  • Up to 18 V operating range, 21 V absolute maximum.
  • Integrated 17 mΩ pass MOSFET.
  • 15 V output voltage clamp.
  • 2 A to 13.5 A adjustable output current clamp.
  • 2 µs short circuit protection response time.
  • Programmable output rise time control.
  • Built-In thermal shutdown with fault alert pin.
  • Fault response options: latch-off, auto-retry.
  • Leadless plastic package; 10 terminals, body 3.0 x 3.0 x 0.75 mm (DFN3030-10/SOT8037.

NPS3102A; NPS3102B 12 V, 2 A to 13.5 A, 17 mΩ eFuse Rev. 1 — 18 July 2024 Product data sheet 1. General description NPS3102A and NPS3102B are low-ohmic (17 mΩ), high current (13.5 A), resettable electronic fuses that are targeted for 12 V applications. They are designed to protect downstream loads from exposure to excessive voltage and protect the power supply from load faults and large inrush currents. Output slew rate is controlled by a capacitor at dVdt pin. Current limit can be adjusted in the 2 A to 13.5 A range using a resistor at ILIM pin. The voltage at ILIM pin can also be used as a measure of the load current in real-time. The devices include a built-in over voltage clamp that will limit the output voltage during input over voltage conditions.
