MX887P

µ Power Hall-Effect Switch

Features: General Description

µPower Operation (15 µW typical at 25°C) The MX887P integratedHall-Effect switch targets the requirementsof low-power portabledevices 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 V Omni polar (switches with N or S pole) 2.5 to 5.5 Volt Operation Simple Digital Output InterfacingCMOS Push-Pull
SUPPLY .The switch output will transition to the Groundpotentialwhen either a north or south magnetic pole is applied. Theremovalof a magnetic field willtransition the switch to the Vsupply potential. Emulating the behavior of a traditional reed switch,together with the advantagesofhigh integration andsolidstatereliability, makes the MX887P is an ideal replacement in low-powerportable deviceapplications. Ultra Low Offset Canceling Amplifiers Provide Sensitive, Accurate, Stable Switching Points and Immunity to Mechanical Stress Solid State Circuitry Operating TemperatureRange: -40°C to +85°C RoHS Compliant TSOT-23 3 Lead Package

Applications:

Handheld Portable Devices
