NIS5135MN1-FN-7

Current Regulation/Management Overview

The NIS5135MN1-FN-7 is an integrated eFuse and power switch manufactured by Diodes Incorporated. It features a self-resetting PPTC mechanism combined with an integrated NMOS for robust load protection against overvoltage, overcurrent, and thermal faults. The device includes an internal charge pump and undervoltage lockout circuitry to ensure reliable operation within a -0.6V to 18V steady-state input range. It provides configurable current limiting via an external resistor on the ILimit pin and manages output rise time through a dv/dt control pin. The component supports both latch and auto-retry thermal protection modes.

Current Regulation/Management Feature Summary

• Integrates power FETs and protection logic without requiring external current shunt resistors
• Includes internal charge pump and undervoltage lockout for stable startup and operation
• Features overvoltage clamping circuitry to limit transient output voltage spikes
• Provides programmable current limit and controlled output rise time via external components

Current Regulation/Management Applications

• Protecting sensitive downstream circuits from input voltage transients
• Power distribution units requiring integrated overcurrent and thermal protection
• Systems needing configurable fault response with latch or auto-retry modes

Current Regulation/Management Procurement Notes

Verify the End-of-Life status and availability constraints before design finalization. Confirm that the FN package variant matches your PCB footprint requirements. Ensure the selected configuration aligns with the required thermal protection mode (latch vs. auto-retry) as defined in the official datasheet specifications.

Current Regulation/Management Selection Notes

Select this component when a compact solution integrating power switching and protection is required. Consider the 68mΩ typical on-resistance for efficiency calculations. Verify that the external resistor values for ILimit and the capacitor for dv/dt meet the specific timing and current threshold requirements of the target application.

Current Regulation/Management Part Context

This part belongs to the NIS5135 series of electronic fuses designed by Diodes Incorporated. The series focuses on providing comprehensive protection for low-voltage applications. The MN1 suffix typically denotes specific pinning or functional variations within the broader product family, distinguishing it from other variants in the same line.

Current Regulation/Management Replacement Considerations

Check for direct substitutes within the NIS5135 series that may offer different thermal protection behaviors or package options. Verify pin compatibility and electrical parameter equivalence before replacing the component in existing designs.
