NCS37010MNTWG

Overview

The NCS37010MNTWG is a specialized Power Management IC designed for Ground Fault Circuit Interrupter (GFCI) applications. It operates within an input voltage range of 6 V to 12 V and provides a regulated output voltage between 4.5 V and 5.5 V. The device delivers an output current of 8 mA with a quiescent supply current of 25 µA. It is housed in a QFN-16 package and supports surface mount installation. The component functions reliably across an operating temperature range from -40 °C to +85 °C.

Feature Summary

• Specialized signal processing for GFCI applications
• Low power consumption design
• Integrated self-test functionality

Applications

• Ground Fault Protection systems
• Self-test circuit breaker implementations

Procurement Notes

Verify the specific suffix MNTWG against official onsemi documentation to confirm packaging details such as reel size or tape specifications. Ensure compatibility with RoHS standards and check for any moisture sensitivity level requirements during storage and handling. Confirm that the QFN-16 footprint matches the target PCB layout dimensions and thermal pad requirements before finalizing procurement orders.

Selection Notes

Select this component when designing GFCI circuits requiring low standby power consumption. The wide input voltage range accommodates various AC line voltages after rectification. Consider the QFN-16 package for compact board space. Verify that the 8 mA output capability meets the load requirements of the downstream protection logic or relay driver stages in the application design.
