The SC4001 linear Hall-Effect device is operated by the magnetic field from a permanent magnet or an electromagnet. The ratiometric output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic. The quiescent output voltage of the SC4001 is 50% of the supply voltage, and the sensitivity is 1.4mV/Gs.
These devices are available in a 3-pin SIP package and a 3-pin TSOT23 package. Both packages are lead(Pb) free, with 100% matte tin leadframe plating.
