NCP382HD10AAR2G

Overview

The NCP382HD10AAR2G is a dual high-side power switch IC from onsemi, designed for load distribution applications. It features two independent P-channel outputs with a maximum continuous output current of 1.5 A and a fixed current limit of 1 A. The device operates within a supply voltage range of 2.5 V to 5.5 V and exhibits a maximum on-resistance of 140 mΩ. Key timing parameters include a maximum turn-on time and idle time of 3 ms each. It is housed in an 8-SOIC package and supports surface-mount installation.

Feature Summary

• Dual high-side switching capability with integrated overcurrent protection
• Controlled slew rate functionality to minimize inrush current during activation
• Integrated thermal shutdown circuitry for enhanced operational safety
• Status flag output providing real-time fault indication

Applications

• Load distribution in industrial control systems
• Power management in automotive infotainment units
• Peripheral power switching in embedded computing platforms

Procurement Notes

Verify component authenticity through authorized onsemi distributors or certified partners. Confirm the specific ordering suffix matches the required package and tape/reel configuration. Check for recent Product Change Notices regarding manufacturing site updates or material declarations. Ensure compliance with RoHS and REACH regulations as specified in the official datasheet before integration into final assemblies.

Selection Notes

Select this component when dual-channel high-side switching with precise current limiting is required. The 1 A current limit suits moderate-load applications where surge protection is critical. Consider the 140 mΩ on-resistance for thermal management calculations. Verify that the 2.5 V to 5.5 V operating voltage aligns with the system logic levels and load requirements.

Part Context

This part belongs to the NCP382 family of power switches, which offers various current ratings and package options. It serves as a robust solution for protecting downstream loads from short circuits and overloads. The series is commonly utilized in environments requiring reliable power sequencing and distribution with minimal external component count.

Replacement Considerations

Direct substitutes within the same family include NCP382HD05AAR2G for lower current needs and NCP382HD15AAR2G for higher capacity. Verify pin compatibility and electrical specifications before substitution.
