AFE3010AIRGTT

Specialized ICS Overview

The AFE3010AIRGTT is a single-chip Ground Fault Circuit Interrupter (GFCI) controller designed to aid in the development of UL-943 compliant systems. It features built-in self-test capabilities for end-of-life detection, ground fault leakage path monitoring, and neutral-ground leakage detection. The device integrates dual VDD/GND pins for redundancy and an onboard shunt regulator that powers the system through passive components. It supports 120-V/60-Hz and 220-V/50-Hz AC systems with an operating temperature range from -40°C to 105°C. The component utilizes a current-feedback chopper amplifier topology for precise fault sensing.

Specialized ICS Feature Summary

• Integrated self-test functionality detects component failures, triggers LED indicators, and trips the load switch via SCR driver.
• Dual VDD and GND pins provide redundancy against single-component failure events.
• Fast response times ranging from 10 ms at ±50 mA to 150 ms at ±5 mA ground fault currents.
• Unique closed-loop neutral-ground leakage detection scheme eliminates the need for component resonance tuning.

Specialized ICS Applications

• GFCI Outlet Receptacles
• GFCI Circuit Breakers
• In-Line Power Cords

Specialized ICS Procurement Notes

Verify the specific suffix 'RGT' corresponds to the 16-pin VQFN package with exposed pad and wettable flank capability. Confirm the reel quantity matches the required production volume, as standard packaging may vary between cut tape and full reels. Ensure compliance with moisture sensitivity levels during storage and handling prior to soldering.

Specialized ICS Selection Notes

Select this component when designing systems requiring simultaneous protection against hot-to-ground and neutral-to-ground faults. The adjustable fault current thresholds via external feedback resistors allow customization for specific regulatory requirements. Consider the integrated noise filter and fast response times for applications demanding high reliability against false trips.

Specialized ICS Part Context

The AFE3010AIRGTT belongs to the AFE3010 series of specialized ICs manufactured by Texas Instruments. It is categorized under board mount surge protectors and GFCI controllers. The device is housed in a 16-VQFN (3x3 mm) package, suitable for surface-mount assembly. It serves as a precision, low-power solution for detecting leakage paths in electrical circuits to prevent electric shock hazards.

Specialized ICS Replacement Considerations

No publicly confirmed substitute part numbers are available in the provided documentation. Designers should evaluate pin compatibility and functional equivalence if considering alternative GFCI controllers from other manufacturers.
