NCV47823PAAJR2G

Overview

The NCV47823PAAJR2G is a dual high-side power switch IC from onsemi, designed for robust power distribution in automotive and industrial environments. It features two independent output channels capable of delivering up to 250 mA continuous current with a 350 mA current limit. The device operates within a supply voltage range of 4.4 V to 40 V, with a typical operating voltage of 13.5 V. It supports fast switching with a maximum turn-on time of 25 µs and functions reliably across an extended temperature range from -40°C to +150°C. Packaged in a TSSOP-14 surface-mount format, it meets AEC-Q101 automotive qualification standards.

Feature Summary

• Dual-channel high-side switching architecture for independent load control
• Automotive-grade reliability certified under AEC-Q101 standards
• Integrated current limiting protection to safeguard connected loads
• Extended thermal performance suitable for harsh operating environments

Applications

• Automotive body electronics load distribution
• Industrial motor control systems
• General-purpose power switching in vehicle networks

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade specifications. Confirm that the required output current does not exceed the 250 mA continuous rating per channel. Check datasheet limits for junction temperature management when operating near the 150°C maximum. Ensure input voltage remains within the 4.4 V to 40 V operational window for stable performance.

Selection Notes

Select this component when dual isolated high-side switching is required in space-constrained designs. The TSSOP-14 package offers a compact footprint compared to larger DIP options. Consider the 250 mA per-channel limit against total system load requirements. The AEC-Q101 certification makes it suitable for applications requiring automotive reliability standards without needing additional ruggedization.

Part Context

This device belongs to the NCV47823 series of protected high-side switches. It complements other onsemi power management solutions by providing simple digital control interfaces for multiple loads. The series is designed to replace discrete MOSFET arrangements, reducing board space and simplifying design complexity in power distribution networks.

Replacement Considerations

Check for pin-compatible alternatives within the same family that may offer different current ratings or packaging options. Verify functional equivalence regarding logic levels and protection thresholds before substituting.
