NIS5135MN2TXG

Current Regulation/Management Overview

The onsemi NIS5135MN2TXG is a 5V electronic fuse housed in a DFN-10 package. It integrates power FETs to provide overcurrent and thermal protection without external shunts. Key electrical parameters include a maximum voltage of 5 VDC, a rated current of 3.6 A, and an on-resistance of 82 mOhms. The device operates within a temperature range of -40°C to +150°C.

Current Regulation/Management Feature Summary

• Integrated power devices eliminate the need for external current shunt resistors.
• Internal charge pump and undervoltage lockout ensure stable operation under varying input conditions.
• Overvoltage clamp circuit limits output voltage during transients to protect downstream loads.
• Built-in dv/dt control manages output rise rates to prevent inrush current issues.

Current Regulation/Management Applications

• Protection of sensitive load circuits against input voltage spikes
• Current limiting in portable electronic devices
• Bus protection in industrial equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix 'MN2' against the manufacturer datasheet to confirm the exact thermal protection behavior (e.g., latch vs. auto-retry) and pin configuration. Ensure the component meets RoHS standards and lead-free requirements for your assembly process. Cross-reference the DFN-10 footprint with your PCB design guidelines.

Current Regulation/Management Selection Notes

Select this part when a compact solution for 5V bus protection is required. The integrated design reduces bill of materials by removing external shunts. Consider the 82 mOhm resistance for efficiency calculations. Verify that the 3.6 A rating aligns with the maximum load current requirements of the target application.
