onsemi PMIC - Power Management - Specialized FAN4149M6X

The FAN4149M6X is a low-power ground fault interrupter controller designed for detecting hazardous current paths to ground and ground-to-neutral faults. It meets the 2015 UL943 self-test requirements when used with the FAN41501 digital controller. The device features a precision sense amplifier, a bandgap reference, and a built-in noise filter, which enhances its reliability in various applications. With a quiescent current of 500 ¬µA, the FAN4149M6X operates efficiently, making it suitable for both 120 V and 220 V systems. Its compact SOT23, 6-pin package minimizes the number of external components required, facilitating a space-saving design. The controller is ideal for applications such as GFCI output receptacles, circuit breakers, and portable GFCI cords. The device operates within a temperature range of -35¬8C to +85¬8C, providing versatility for different environmental conditions.
