NCS37015

Self Test Ground Fault Circuit Interrupter (GFCI) NCS37015 The NCS37015 is a UL943 compliant signal processor for GFCI applications with self test. The device integrates a flexible power supply (including a 12 V shunt and two 3.3 V internal series regulators), differential fault, and grounded−neutral detection circuits. Self test is monitored at start up and then every 17 minutes. Features Meets UL943 Self−test GFCI Requirements 4.0 – 12 Volt Operation (120−480 V AC mains with the appropriate series impedance) −40°C to 95°C Typical 575 mA Quiescent Current @ 11 V 16 Pin QFN Inverted and Latched SCR Output to Facilitate a Solenoid Operation Self Syncing Internal Oscillator adjusts to AC Mains Frequency to Guarantee Full Resolution on 60 Hz Distribution Systems Optimized Solenoid Deployment (coil is not energized near the AC mains zero crossings) Power Supply Monitor that Verifies Full Diode Bridge Operation Tiered Trip Times that Increase Immunity to Noise Under−voltage Detection that Allows for Increased Operation at Lower AC Input Voltages Typical Applications Portable GFCI Plugs GFCI Receptacles www.onsemi.com QFN16 CASE 485FQ PIN ASSIGNMENT GNE TE SCR PTT CTG GFT CTB CTS LED MLD SUP RES CTO IDF VDA GND (Top View) MARKING DIAGRAM 37015 ALYWG G 37015 A L Y W G = Specific Device Code = Assembly Location = Wafer Lot = Year = Work Week = Pb−Free Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering a...
