External magnetic field on each axis not continuously higher than 16G.
Supply current is proportional to how many measurements performed per second, 75Hz (maximum) for BW=00.
Based on 3lots characterization result.
The 1000 Hz ODR is available by writing 255 into Register ODR and setting hpower to 1.
MEMSIC product enables users to utilize heading accuracy to be 1.0 degree typical when using MEMSIC’s proprietary software or algorithm.
Sensitivity of the orthogonal axes is analytically derived from raw data and is subsequently processed by MEMSIC software drivers.
This is the magnitude of external field that can be tolerated without changing the sensor characteristics. If the disturbing field is exceeded, a SET/RESET
operation is required to restore proper sensor operation.
Based on shipment test result.

THEORY OF OPERATION
The Anisotropic Magneto-Resistive (AMR) sensors are
special resistors made of permalloy thin film deposited
on a silicon wafer. During manufacturing, a strong
magnetic field is applied to the film to orient its magnetic
domains in the same direction, establishing a
magnetization vector. Subsequently, an external
magnetic field applied perpendicularly to the sides of
the film causes the magnetization to rotate and change
angle. This effect causes the film’s resistance to vary
with the intensity of the applied magnetic field. The
MEMSIC AMR sensor is incorporated into a
Wheatstone bridge configuration to maximize Signal to
Noise ratio. A change in magnetic field produces a
proportional change in differential voltage across the
Wheatstone bridge
However, the influence of a strong magnetic field (more
than 30 G) in any direction could upset, or flip, the
polarity of the film, thus changing the sensor
characteristics. A strong restoring magnetic field must
be applied momentarily to restore, or set, the sensor
characteristics. The MEMSIC magnetic sensor has an
on-chip magnetically coupled strap: a SET/RESET
strap pulsed with a high current, to provide the restoring
magnetic field.
All parts are shipped in tape and reel packaging with
10000pcs (or 5000pcs per requested) per 7” reel.

This is an Electro-static Discharge (ESD) sensitive

EXTERNAL CIRCUITRY CONNECTION
The MMC5603NJ can operate from a single 1.62V to
3.6V supply. The circuit connection diagrams below
illustrate power supply connection options.
Details please refer to MEMSIC Magnetic Sensor
Hardware Design Layout Guideline for Electronic
Device.
POWER CONSUMPTION
The power consumed by the device is proportional to
the number of measurements taken per second. For
example, when BW<1:0>=10, MMC5603NJ consumes
1.3mA (typical) at 1.8V with 100 measurements per
second. If only 1 measurements are performed per
second, the current will be 1300*1/100=13µA.

C INTERFACE DESCRIPTION
A slave mode I
2
C circuit has been implemented into the
MEMSIC magnetic sensor as a standard interface for
customer applications. The A/D converter functionality
have been added to the MEMSIC sensor, thereby
increasing ease-of-use, and lowering power
consumption, footprint and total solution cost.
The I
2
C (or Inter IC bus) is an industry standard bi-
directional two-wire interface bus. A master I
2
C device
can operate READ/WRITE controls to 128 devices by
device addressing. The MEMSIC magnetic sensor
operates only in a slave mode, i.e. only responding to
calls by a master device.

HARDWARE DESIGN CONSIDERATION
Provide adequate separation distance to devices
that contain permanent magnets or generate
magnetic fields (e.g. speakers, coils, inductors)
The combined magnetic field to be measured and
interference magnetic field should be less than the
full scale range of the MMC5603NJ (±30 G).
Provide adequate separation distance to current
carrying traces. Do not route current carrying
traces under the sensor or on the other side of the
PCB opposite the device.
Do not cover the sensor with magnetized material
or material that may become magnetized, (e.g.,
shield box, LCD, battery, iron bearing material).
Do not place the device opposite magnetized
material or material that may become magnetized
located on the other side of the PCB.
The two wires in the I
2
C bus are called SDA (serial data
line) and SCL (serial clock line). In order for a data
transfer to start, the bus has to be free, which is defined
by both wires in a HIGH output state. Due to the open-
drain/pull-up resistor structure and wired Boolean
“AND” operation, any device on the bus can pull lines
low and overwrite a HIGH signal. The data on the SDA
line has to be stable during the HIGH period of the SCL
line. In other words, valid data can only change when
the SCL line is LOW.
