Melexis US1883LUA-AAA-000-BU

The Melexis US1883 is a Hall-effect latch designed using mixed-signal CMOS technology. The device integrates a voltage regulator, a Hall sensor with a dynamic offset cancellation system, a Schmitt trigger, and an open-drain output driver in a single package. Its wide operating voltage range and high temperature rating make it well-suited for automotive, industrial, and consumer applications. The device is available in a plastic single in-line (TO-92 flat) package for through-hole mounting and is RoHS compliant. Based on mixed-signal CMOS technology, the Melexis US1883 is a Hall-effect device with medium magnetic sensitivity. This versatile latch meets the requirements of most applications. The chopper-stabilized amplifier employs switched-capacitor techniques to suppress the offset voltages typically associated with Hall sensors and amplifiers. CMOS technology enables this advanced approach, helping to reduce die size and current consumption compared to bipolar technology. The smaller die size also plays an important role in minimizing the effects of mechanical stress. This combination results in more stable magnetic characteristics and enables faster, more precise designs. A wide operating voltage range of 3.5V to 24V, low current consumption, and a high operating temperature range per the "L" specification make the device suitable for automotive, industrial, and consumer applications. The output signal is open-drain type; by connecting a pull-up resistor between the pull-up voltage and the device output, this output can be easily interfaced with TTL or CMOS logic.
