GF4149 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD Preliminary LINEAR INTEGRATED CIRCUIT GROUND FAULT INTERRUPTER - DESCRIPTION The UTC GF4149 is a low-power controller for detecting hazardous current paths to ground and ground-to-neutral faults. The UTC GF4149 application circuit opens the load contacts before a harmful shock occurs. The UTC GF4149 contains a precision bandgap 14V shunt regulator, precision low-VOS sense amplifier, time-delay noise filter, window-detection parators, and an SCR driver. The SCR driver provides increased current and temperature pensation to allow for a wider selection of external SCRs. - Features - Precision Sense Amplifier and Bandgap Reference - Low-VOS Offset - Built-in Noise Filter - High-Current SCR Gate Driver - Adjustable Sensitivity - Low Quiescent Current - Minimum External ponents - Ideal for 120V or 220V Systems - ORDERING INFORMATION Ordering Number Lead Free Halogen Free GF4149L-AG6-R GF4149G-AG6-R 54 6 1 23 SOT-26 Package SOT-26 Packing Tape Reel GF4149G-AG6-R (1)Packing Type (2)Package Type (3)Green Package (1) R: Tape Reel (2) AG6: SOT-26 (3) G: Halogen Free and Lead Free, L: Lead...
