NCP380HSN10AAT1G

Overview

The NCP380HSN10AAT1G is a high-side power distribution switch from onsemi, designed for applications with heavy capacitive loads and potential short circuits. It integrates a P-channel MOSFET with a typical on-resistance of 70 mΩ in the TSOP-5 package. The device operates within a voltage range of 2.5V to 5.5V and supports a maximum output current of 1A. It features fixed current limiting, UVLO, thermal shutdown, and reverse voltage protection. The FLAG pin provides status indication for fault conditions.

Feature Summary

• Integrates a P-channel MOSFET with controlled rise and fall times to minimize current ringing during switching events.
• Provides comprehensive protection including fixed current limiting, under-voltage lockout, thermal shutdown, and reverse voltage detection.
• Features a logic-controlled enable input and a FLAG output that indicates over-current, reverse voltage, or over-temperature faults.

Applications

• Power distribution in systems with heavy capacitive loads
• High-side switching for load protection against shorts
• Current-limited power routing in portable electronics

Procurement Notes

Verify the specific suffix 'HSN' corresponds to the TSOP-5 package and 1A fixed current limit configuration as documented in the official datasheet. Confirm RoHS compliance and material declaration status through onsemi's official channels. Ensure the ordering part number matches the exact electrical specifications required for the target application circuit design.

Selection Notes

Select this component when a fixed 1A current limit is sufficient for the load requirements. The TSOP-5 package offers a compact solution compared to larger DFN options. Consider the 70 mΩ on-resistance for power dissipation calculations. This part is suitable where controlled slew rates are needed to prevent inrush current issues on capacitive loads.

Part Context

The NCP380 series includes variants with adjustable or fixed current limits and different packages. The HSN suffix specifically denotes the TSOP-5 package with a fixed 1A limit. Other series members like NCP380HMU offer higher current ratings or adjustable limits in uDFN packages. This model is part of the broader NCP/NCV380 family of high-side switches.

Replacement Considerations

Direct substitutes include other NCP380 variants with similar current limits but different packages, such as NCP380LSN10AAT1G if LSNAJAAT1G compatibility is not required. Verify package dimensions and pinout compatibility before substitution. No other direct cross-model replacements are confirmed in public documentation.
