DESCRIPTION
The MMC5983MA is an AEC-Q100 qualified complete
3-axis magnetic sensor with on-chip signal processing
and integrated I
2
C/SPI bus suitable for use in
automotive applications. The device can be connected
directly to a microprocessor, eliminating the need for
A/D converters or timing resources.
It can measure magnetic fields within the full scale
range of 8 Gauss (G), with 0.25mG/0.0625mG per
LSB resolution at 16bits/18bits operation mode and 0.4
mG total RMS noise level, enabling heading accuracy
of 0.5º in electronic compass applications.
An integrated SET/RESET function provides for the
elimination of error due to Null Field output change with
temperature. Temperature information from the
integrated temperature sensor is available over the I
2
C
Interface. The SET/RESET function can be performed
for each measurement, periodically, or when the
temperature changes by a predetermined amount as
the specific application requires.
In addition, the SET/RESET function clears the sensors
of any residual magnetic polarization resulting from
exposure to strong external magnets.
The MMC5983MA is packaged in a low profile LGA
package and an operating temperature range from -
40C to +105C.
The MMC5983MA provides an I
2
C digital output with
400 KHz, fast mode operation, and a 10MHz SPI digital
output.
