Overview

NCS37012 Self Test Ground Fault Circuit Interrupter (GFCI) Description The NCS37012 is a fully UL943 compliant signal processor for GFCI applications with self test.
The device integrates a flexible power supply (including both shunt and LDO regulators), differential fault, and grounded-neutral detection circuits.
Proprietary impedance measurement and signal processing techniques are used to minimize the number of external components and improve performance.
The device also includes a specialized DSP controller that offers best in class immunity to nuisance loads without the need for external analog filters.
Self test is monitored every 17 minutes through an external current path and intern...
