Overview

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.

  • UL943 compliant GFCI products with self test

  • Portable GFCI plugs
  • GFCI receptacles

  • Auto monitoring test function required by UL943
  • Self syncing internal oscillator adjusts to AC mains frequency to guarantee full resolution
  • Typical 575 µA Quiescent Current @ 11 V
  • Tiered trip times by the level of ground fault
  • Under voltage detection
  • Inverted and latched SCR output

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
