Product Overview NCS37010: Single CT UL943 GFCI with Self Test and Lockout For complete documentation, see the data sheet Product Description The NCS37010 is a fully UL943 compliant signal processor for GFCI applications with self test and lockout. 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. At power up the NCS37010 performs a self test at 60ms and removes the lockout if the test passes. This self test consists of a differential, ground-neutral and solenoid test. Features Benefits • full self test and electronic lockout • fully compliant with UL self test requirements and minimal BOM impact • compatible with global power AC power systems • self syncing internal oscillator adjusts to AC mains frequency to guarantee full resolution on 50 and 60Hz distribution systems • randomized testing sequence to noise sensitivity and potential interactions on the AC mains • high SCR drive current (up to 5mA) Applications • robust design • compatible with high Igt SCR's for improved noise immunity End Products • UL943 Compliant GFCI products with self test • GFCI receptacles • GFCI circuit breakers • ALCI power cords Part Electrical Specifications Product Compliance Status Channels VCC Min (V) VCC Max (V) IT Max (mA) VI Typ (V) TA Min (°C) TA Max (°C) Package Type NCS37010DBRG Pb-free Active 1 6 12 2.2 1.8 -40 85 TSSOP-20 Active 1 6 12 2.2 1.8 -40 85 QFN-16 Halide free NCS37010MNTWG Pb-free Halide free For more information please contact your local sales support at www.onsemi.com Created on: 6/30/2016
