Low power Hall switch (polar), for mobile phones, torches, PHS, cordless phones, Notebook laptop, PDA flip circuits, intelligent remote water meter, intelligent remote gas meter counting, Shenzhen City Hall Micro Electronics (http://www.hallwee.com) offers a full pole Hall element latest offer also includes an all-pole Hall element image \ Hall element parameters \ Hall Switch PDF Data \ Hall switch reviews Quotes and other information, as You purchase a Hall element to provide the most valuable reference! to provide you with Hall switch selection guide product development. Hall sensor HAL148 Omnipolar Hall switch Hall element a low-power, all-pole Hall switch 148 is a mixed-signal CMOS technology based on non-polar Hall switch, this IC adopts advanced chopper stabilization techniques, it is possible to provide accurate and stable magnetic switching points. In the circuit design, low power consumption Hall element 148 provides a controlled clock mechanism to provide a clock source for the Hall element and analog signal processing circuit, but this can be controlled by the clock mechanism control signals current-consuming circuit periodically enter a "sleep" mode; by this mechanism, the chip is periodically "wakes up" and the size of the Hall element pass through the magnetic field strength of the magnetic field strength in accordance with a predetermined threshold detector good outside. If the flux density is higher than the "operating point" threshold or below the "release point" threshold, the open drain output transistor is driven and latched into the Correspondingly state. In the "sleep" cycle, the output transistor is locked in its previous state. In battery-powered applications, this design to extend the working life to provide the best support. Second, the 148 Hall switching characteristics: · 2.4V - 5.5V battery application of magnetic switching points and high sensitivity stability · immunity to mechanical stress · digital output signal which is non-polar switch three, 148 Hall switch Package: SOT -23 TO-92UA Shenzhen City Hall Microelectronics (http://www.hallwee.com) latest offer provides all-pole Hall element 148, also includes all-pole Hall element 148 pictures \ Hall element 148 parameter \ Hall Switch 148 PDF Data \ Hall switch 148 reviews quotes and other information for your purchase of the Hall element 148 to provide the most valuable information! Hall switch selection guide provided for your product development.
