NCS37010DBRG

Overview

The NCS37010DBRG 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 delivers an output voltage between 4.5V and 5.5V. It features a self-test capability with lockout functionality to ensure safety compliance. The device is housed in a 20-TSSOP surface-mount package and supports operation across a temperature range of -40°C to 85°C. With a supply current of 2mA, it offers efficient power management for protective circuitry.

Feature Summary

• Integrated self-test mechanism with automatic lockout for enhanced safety reliability
• Dedicated ground fault protection architecture for compliant circuit interruption
• Surface-mount TSSOP packaging for compact board integration

Applications

• Ground Fault Circuit Interrupter systems
• Safety-critical power management circuits
• Residential and commercial electrical protection devices

Procurement Notes

Verify the specific suffix DBRG confirms the 20-TSSOP package variant, as other suffixes like MNG indicate different packages such as QFN. Confirm lifecycle status, as this part may be subject to obsolescence or end-of-life notices from the manufacturer. Ensure compatibility with existing PCB footprints before procurement, as package dimensions differ significantly from other NCS37010 variants.

Selection Notes

Select this component when a dedicated GFCI solution with integrated self-test and lockout features is required. The 20-TSSOP package is suitable for designs prioritizing through-hole compatible surface mounting over smaller QFN footprints. Verify that the 6V-12V input range aligns with the system's power supply architecture. Consider moisture sensitivity level requirements during storage and reflow soldering processes.

Part Context

The NCS37010 series includes multiple package options, including the MNG variant in a 16-QFN package. The DBRG suffix specifically denotes the 20-TSSOP configuration. This differentiation is critical for design-in, as pinouts and physical dimensions vary between packages despite sharing the same core PMIC functionality for ground fault protection.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate other NCS37010 variants only if package adaptation is feasible. No alternative part numbers are verified as electrically and mechanically interchangeable without schematic and layout modifications.
