MX887P (Data Sheet)
Click here for Reliability Report for this device
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 5μA at 3.0 VSUPPLY. 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 an ideal replacement in low-power portable device applications.
Available in the TSOT23 3-pin package.
