The MX887D 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 VSUPPLY = 3VDC 。 The switch output will turn “on” when either a north or south magnetic pole is applied. The absence of a magnetic field will set the switch into the high-impedance “off” state. Emulating the behavior of a traditional reed switch, together with the advantages of high integration and solid state reliability, makes the MX887D an ideal replacement in low-power portable device applications.
