SC44E  磁性传感器 

The SC44E Hall-Effect switch series is monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150℃, and are more stable with both temperature and supply voltage changes. The negative compensation slope is optimized to match the negative temperature coefficient of low cost magnets. Each device includes a voltage regulator for operation with supply voltages of 3.8 to 40V volts, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to 40mA
