NCS37005MNG

Overview

The NCS37005MNG is a specialized Power Management IC (PMIC) designed for Ground Fault Circuit Interrupter (GFCI) applications. Manufactured by onsemi, this component operates within a supply voltage range of 6V to 12V and draws a typical supply current of 2mA. It is housed in a compact 16-VFQFN package with exposed pad, measuring 3x3 mm, suitable for surface mount installation. The device is rated for an operating temperature range of -40°C to 85°C. This integrated circuit provides essential control functions for detecting ground faults in electrical systems.

Feature Summary

• Integrated controller specifically engineered for GFCI protection circuits
• Compact 16-pin QFN footprint optimized for space-constrained designs
• Operates reliably across extended industrial temperature ranges

Applications

• Ground Fault Circuit Interrupter (GFCI) modules
• Residual Current Device (RCD) implementations
• Electrical safety monitoring systems

Procurement Notes

Verify the obsolete status of the NCS37005MNG before procurement planning. Confirm availability through authorized distributors or secondary markets as standard production may have ceased. Ensure compatibility with existing board layouts when sourcing from alternative suppliers. Check for recent date codes if long-term storage is anticipated. Validate that the 16-QFN package matches the target design constraints.

Selection Notes

Select this component when designing dedicated GFCI controllers requiring low supply current and a small form factor. Consider the 6V-12V input range against available system rails. Evaluate the 16-QFN thermal performance for the specific enclosure environment. Compare against newer onsemi alternatives if long-term supply assurance is critical for the product lifecycle.

Part Context

This part belongs to onsemi's specialized PMIC portfolio focused on power quality and safety. It complements other protection devices by handling the logic and detection aspects of ground fault monitoring. The NCS37005 series is distinct from general-purpose regulators, targeting niche safety compliance requirements in residential and commercial electrical infrastructure.

Replacement Considerations

Check for direct pin-compatible upgrades within the NCS370xx family. Verify functional equivalence with newer GFCI controllers from onsemi or competitors. Ensure replacement parts support the same 16-QFN(3x3) package dimensions.
