FAN4147SX

Power Management - Specialized Overview

The FAN4147SX is a Ground Fault Interrupter (GFI) controller manufactured by onsemi, designed for AC power line protection applications. It operates within a supply voltage range of up to 2.5 V and draws a maximum operating current of 0.5 mA. The device features a single output and is housed in a compact SOT-23 package with six pins, measuring 3 x 1.7 x 1 mm. It supports surface mount installation and functions reliably across an extended temperature range from -35 °C to +85 °C.

Power Management - Specialized Feature Summary

• Integrated GFI controller functionality for AC power line safety
• Ultra-low power consumption suitable for battery-operated systems
• Compact SOT-23 surface-mount packaging for space-constrained designs

Power Management - Specialized Applications

• AC power line ground fault protection circuits
• Battery-powered safety monitoring devices
• Portable electrical equipment requiring low standby current

Power Management - Specialized Procurement Notes

Verify the specific suffix SX against official datasheets to confirm pinout and thermal characteristics. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure design compatibility with the specified 2.5 V maximum operating voltage and 0.5 mA current limits for target application requirements.

Power Management - Specialized Selection Notes

Select this component when designing AC ground fault protection systems requiring minimal quiescent current. The SOT-23-6 package offers a small footprint ideal for portable or densely populated PCB layouts. Verify that the operating temperature range of -35 °C to +85 °C meets environmental conditions. Compare against similar controllers like the FAN4146ESX if different packaging or temperature ratings are required.

Power Management - Specialized Part Context

The FAN4147SX belongs to onsemi's portfolio of specialized Power Management ICs (PMIC). It complements other GFI solutions such as the FAN4146 series, providing designers with options for different package styles and operational parameters within the same functional category of AC line protection controllers.

Power Management - Specialized Replacement Considerations

The FAN4146ESX is a related GFI controller from onsemi. Verify pin compatibility and package differences (SuperSOT-6 vs SOT-23) before substitution. Check for any changes in operating temperature ranges or supply current specifications between these variants.
