ower Hall-Effect Switch

The MX887P integrated Hall-Effect Switch targets the requirements of low-power portable devices with battery operating voltages from 2.5V to 5.5V. On- chip Power Management circuitry reduces the effective average current to just 5A at 3.0 SUPPLY. The Switch output will transition to the Ground potential when either a north or south magnetic pole is applied. The removal of a magnetic field will transition the Switch to the Vsupply potential. Emulating the behavior of a traditional reed Switch together with the advantages of high integration and solid state reliability, makes the MX887P is an ideal replacement in low-power portable device applications.
