  • LOW FREQUENCY DETECTOR INCLUDING COMMON INPUT VOLTAGE SENSOR
    Publication number: 20080186057
    Abstract: A low frequency detector circuit includes a differential input that is received by an offset comparator circuit. The offset comparator circuit provides respective output signals COMPX and COMPY which can be compared to a generated threshold voltage Vcomp by an E2C (ECL to CMOS) comparators. The outputs of the E2C comparators are used by respective timers to generate fault signals. In addition to detecting low frequency conditions, common voltage conditions can be detected as well and can be distinguished at very high frequency conditions.
