NPS3102B - 12V eFuse

Download the NPS3102B datasheet PDF. This datasheet also covers the NPS3102A variant, as both devices belong to the same 12v efuse family and are provided as variant models within a single manufacturer datasheet.

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.

Key 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.
