The MX887D 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 5A at VSUPPLY = 3VDC .

The switch output will turn “on” when either a north or
south magnetic pole is applied. The absence of a
magnetic field will set the switch into the
high-impedance “off” state. Emulating the behavior of
a traditional reed switch, together with the advantages
of high integration and solid state reliability, makes the
MX887D an ideal replacement in low-power portable
device applications.

2 Circuit Description
The MX887D Power Hall-Effect Switch consists of a
Hall element, small signal amplifier, latch, and
N-channel open-drain output. Offset cancellation
circuitry rejects errors in signal stages and the
influence of mechanical stress on the Hall element.
This technique, together with a precision threshold
4
generator and comparator, produces highly accurate
magnetic switch points. The Hall element is activated
for a small fraction of an operating cycle, then latched
in that sample state for the remainder of the period. By
using this technique, very low power consumption is
achieved.

3 Manufacturing Information
3.1 Moisture Sensitivity
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated
Circuits Division classified all of its plastic encapsulated devices for moisture sensitivity according to the
latest version of the joint industry standard, IPC/JEDEC J-STD-020, in force at the time of product
evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee
proper operation of our devices when handled according to the limitations and information in that standard as well as
to any limitations set forth in the information or standards referenced below.
Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced
product performance, reduction of operable life, and/or reduction of overall reliability.
This product carries a Moisture Sensitivity Level (MSL) rating as shown below, and should be handled according to
the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-033.

3.4 Board Wash
IXYS Integrated Circuits Division recommends the use of no-clean flux formulations. However, board washing to
remove flux residue is acceptable, and the use of a short drying bake may be necessary. Chlorine-based or
Fluorine-based solvents or fluxes should not be used. Cleaning methods that employ ultrasonic energy should not be
used.
