MX887P
μPower Hall-Effect Switch
Description
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 V_SUPPLY = 3V_DC .
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 V_SUPPLY 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.
