A 457-8534-004, otherwise known as Zero Cross Detectors, is an integrated circuit manufactured by PrimeParts. It is a general purpose, low-cost single-supply voltage detector. The chip consists of an input amplifier, control voltage, and output amplifier. It is used in a broad array of industrial, consumer, and automotive applications, ranging from automotive and military electronics to medical and safety instrumentation.The primary purpose of Zero Cross Detectors is to detect and detect or ‘zero’ the levels of input voltage that indicate a change in the load being driven by the device in which the detector is installed. It is commonly used as a trigger signal for various components, such as relays, motors, solenoids, and lamps. It also enables the electronic circuits it’s connected to to remain ‘quiet’ when no load is imposed, while simultaneously responding quickly to the onset of any new voltage. This signal can be used as a measure of the current load placed on the device.The working principle of the Zero Cross Detectors is simple. It takes the input signal, typically AC, and amplifies the input voltage level to a maximum of 2500V. The output voltage is then detected by a voltage comparator. Depending on the configuration, the output is either low or high. When the output is low, this can be used as a trigger for various devices, depending on the application. When the output is high, this can be used to detect the termination of a load or indicate a pre-determined voltage level. The device is designed to be very accurate, with detection accuracy levels of as much as 1/10,000th. It also exhibits very low voltage drop and low frictional noise, both of which are important features for certain applications. It is also great for power-sensitive applications, as its no-load current consumption amounts to only 500µA.The Zero Cross Detectors comes in standard 8-pin dual inline packages and has a wide range of supply voltage options. It supports both AC and DC input supply voltages, including 5V, 6V, 9V, 12V, 24V, and 48V. The device operates over a temperature range of -40 to 85°C, with minimal decrease in accuracy over the temperature range. In summary, the Zero Cross Detectors is a versatile, efficient, and reliable component, with a broad range of application in consumer, industrial, and automotive electronics. With its low voltage threshold detection and noise-quenching features, the device is well suited for applications involving low voltage motor control, electric motors, solenoids, and other active circuit components.
