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 VSUPPLY = 3VDC .

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.
