NCP382HD05AAR2G

Overview

The NCP382HD05AAR2G is a dual high-side power switch IC from onsemi, designed for load switching applications. It features two P-channel outputs with a maximum continuous current of 500mA per channel. The device operates within a supply voltage range of 2.5V to 5.5V and utilizes an 8-SOIC surface-mount package. Key electrical parameters include a typical on-resistance of 80mΩ and a fixed current limit protection mechanism. It supports non-inverting input control and includes integrated fault protection against over-temperature conditions.

Feature Summary

• Dual high-side P-channel power switches for independent load control
• Integrated fixed current limit and thermal shutdown protection
• Controlled slew rate to minimize inrush current during turn-on
• Status flag output for monitoring switch state and fault conditions

Applications

• Power distribution systems requiring dual isolated loads
• Embedded systems needing protected high-side switching
• Industrial equipment load management circuits
• Automotive electronics peripheral power gating

Procurement Notes

Verify the specific suffix AAR2G confirms the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status and REACH material declarations are current for your region. Check for any recent Product Change Notices (PCN) regarding package revisions or manufacturing site changes that may impact long-term availability or solderability profiles.

Selection Notes

Select this component when dual independent high-side switching with moderate current capacity is required. Ensure the application load does not exceed the 500mA per channel limit under all operating conditions. Verify that the system voltage remains within the 2.5V to 5.5V operational range. Consider the 80mΩ on-resistance for power dissipation calculations in high-duty-cycle scenarios.

Part Context

This part belongs to the NCP382 family of power distribution switches. It shares functional similarities with variants like NCP382HD10AAR2G but offers lower current handling capability. The NCP382 series is designed for robust load protection in compact packages, serving as a reliable solution for protecting downstream components from short circuits and overloads in low-voltage digital systems.

Replacement Considerations

Direct substitutes within the same family include NCP382HD10AAR2G for higher current needs or NCP382LD10AAR2G for different pinout configurations. Cross-manufacturer replacements require careful verification of pin compatibility, threshold voltages, and protection characteristics to ensure circuit integrity without redesign.
