General Description
The MX8871D integrated Hall-Effect switch targets
battery operating voltages from 2.5V to 5.5V. On-
chip power management circuitry reduces the
effective average current to just 125µA at 3.0
V
The switch output will turn “on” when either a north
or south magnetic pole is applied. The absence of a
magnetic field will turn the switch into a high
impedance “off” state.
Applications:
• White Goods
• Automotive
• Security Systems
• High Reliability Reed Switch Replacement

... Ground Circuit Description The MX8871D Hall-Effect Switch consists of a Hall element, small signal amplifier, latch, and n-channel open drain MOSFET driver. Offset cancellation rejects errors in signal stages and the influence of mechanical stress on the Hall element. This technique together with a precision threshold generator and comparator produce highly accurate magnetic switch points ...
