DATA SHEET www.onsemi.com Self Test Ground Fault Circuit Interrupter (GFCI) NCS37014 The NCS37014 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.
