七悅科技，專注霍爾，您身邊的霍爾芯片專家！

深圳市七悅科技有限公司，專業(yè)從事磁控霍爾開關的研發(fā)和銷售。

深圳七悅科技為你優(yōu)選海量完整的七悅霍爾開關OCH1902，支持上海在線實時詢價。

   The OCH1902 is small, versatile linear Hall effect devices which are operated by the magnetic field from a permanent magnet or an electromagnet. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. These devices

have a quiescent output voltage that is 50% of the supply voltage.

       The Hall-effect integrated circuit included in each device includes a Hall sensing element, a linear amplifier, and a CMOS Class AB output structure. Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.

       High precision in output levels is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process. The integrated circuitry provides increased

temperature stability and sensitivity, for both linear target motion and rotational motion. These linear position sensors have an operating temperature range of -40°C to +125°C, appropriate for industrial environments. They respond to either positive or negative gauss, monitoring either or both magnetic poles. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. The positive temperature coefficient of the sensitivity helps compensate for the negative temperature coefficients of low cost magnets, providing a robust design over a wide temperature range.

       The OCH1902 is available in small 3-pin SOT23 and SIP package, and is rated over the -40°C to +125°C. These packages are available in a lead (Pb) free version.
