NCV8445DR2G

Overview

The NCV8445DR2G is a self-protected high-side power switch IC from onsemi, designed for robust load distribution in automotive and industrial environments. It features a single output channel capable of delivering up to 2 A continuous current with a peak limit of 6 A. The device operates within a supply voltage range of 6 V to 36 V and exhibits a maximum on-resistance of 90 mOhms. It includes integrated protection mechanisms such as overcurrent, overtemperature, and undervoltage lockout. The component is qualified to AEC-Q101 standards and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrated self-protection circuitry providing automatic response to fault conditions including overcurrent and thermal events.
• High-side switching capability optimized for driving inductive and capacitive loads with defined rise and fall times.
• Automotive-grade qualification ensuring reliability under harsh environmental conditions and extended temperature ranges.

Applications

• Automotive lighting systems requiring high-side control and protection
• Solenoid and valve driver circuits in vehicle power distribution modules
• Industrial motor control interfaces needing isolated high-side switching

Procurement Notes

Verify the specific suffix DR2G corresponds to the SOIC-8 tape-and-reel packaging configuration required for your assembly line. Confirm that the AEC-Q101 automotive qualification aligns with your system's reliability standards. Ensure input voltage levels remain strictly within the 6 V to 36 V operational window to prevent device malfunction or damage during procurement validation.

Selection Notes

Select this component when a single-channel high-side switch with integrated fault protection is required. It is suitable for applications demanding low on-resistance to minimize power dissipation while handling moderate current loads. Consider the SOIC-8 package constraints for PCB layout and thermal management capabilities relative to the expected power dissipation of 1.183 W under full load conditions.

Part Context

This part belongs to the NCV8445 series of smart high-side drivers manufactured by onsemi. These devices are engineered to replace discrete MOSFET solutions, offering reduced board space and enhanced diagnostic features. The series is widely utilized in automotive electronics where reliability and compact form factors are critical design parameters.

Replacement Considerations

Check for direct cross-reference part numbers from onsemi or other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute maintains the same AEC-Q101 qualification and SOIC-8 package dimensions to ensure mechanical compatibility without redesigning the footprint.
