NCS37000
Ground Fault Circuit
Interrupter (GFCI)
Description
The NCS37000 is a fully UL943 compliant signal processor for GFCI applications.
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.
