NCS37012DBG

Overview

The NCS37012DBG is a specialized Power Management IC (PMIC) designed for Ground Fault Protection. It operates within a supply voltage range of 6V to 12V and functions across an operating temperature range of -40°C to +85°C. The component is housed in a 20-TSSOP surface-mount package with a width of 4.40mm. It features a low current supply of 30μA, ensuring minimal power consumption during operation.

Feature Summary

• Integrated ground fault detection capabilities for safety compliance
• Low quiescent current consumption of 30μA for energy efficiency
• Built-in self-test functionality with lockout mechanisms

Applications

• Ground Fault Circuit Interrupter (GFCI) systems
• Residential and commercial electrical safety devices
• Portable battery-powered safety equipment

Procurement Notes

Verify the specific suffix 'DBG' against official onsemi documentation to confirm pinout and thermal specifications. Ensure compatibility with the required 20-TSSOP footprint and validate that the 6V-12V input range matches the target circuit design before procurement.

Selection Notes

Select this PMIC when compact surface-mount integration is required for ground fault protection. The 20-TSSOP package suits space-constrained designs. Verify that the 6V-12V operating range aligns with the system's power supply architecture and that the -40°C to +85°C temperature rating meets environmental requirements.

Part Context

This component belongs to the NCS3701x series of specialized PMICs from onsemi. It is engineered specifically for GFCI applications, offering integrated protection logic. The device simplifies design by combining fault detection and control functions into a single surface-mount package, reducing component count compared to discrete solutions.

Replacement Considerations

The NCS37010MNTWG is a documented variant within the same family featuring similar self-test and lockout functions. Verify pin-to-pin compatibility and specific parameter tolerances before substitution.
