GF4149 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.
