AFE3010 Ground Fault Circuit Interrupter (GFCI) With Self-Test and Neutral-Ground Fault Detection

1 Features

Single-chip GFCI controller to aid in the design of UL-943 compliant systems
- Built-in self-test to detect end-of-life, blink the LED, and/ or trip the load switch
- Detect ground fault leakage path, and trip the load switch
- Detect neutral-ground leakage path, and trip the load switch
Protection against single-component failure
Dual VDD and GND pins for redundancy
Integrated noise filter to prevent false trips
Simultaneously protects against HOT to GND and neutral to GND faults
Adjustable fault current thresholds through external feedback resistors
Fast response time
- 150 ms for ±5mA ground fault current
- 85 ms for ±10-mA ground fault current
- 40 ms for ±30-mA ground fault current
- 10 ms for ±50-mA ground fault current
Onboard shunt regulator powers the system through passives
Supports 120-V/ 60-Hz or 220-V/ 50-Hz systems
Operating temperature range: –40 ºC to 105 ºC
