ROHM Hall Effect Sensor ICs

ROHM Hall Effect Sensor ICs The demands for extended battery operation, greater reliability and increased features are driving the designs of mobile phones, notebook computers, video cameras, navigation systems and game controllers to use smaller, higher performance components.

Ultra-small, hall effect, non-contact switches from ROHM Electronics can simplify and enhance your designs while offering the benefits of high-reliability and low power consumption. These high performance devices are the ideal choice for a range of switch applications:

        •    Portable phone or PDA in or out of its carrying case
        •    Slide open or closed on cell phone or camera
        •    Flip phone or laptop cover open or closed
        •    Cell phone or tablet PC screen orientation
        •    Track wheel position on MP3 players, toys and games
