Description
The MLX91210 is an Integrated Current Sensor
that senses the current flowing through the
leadframe of the SOIC package. The current
conductor exhibits low power dissipation (0.7 -
0.8mΩ). By virtue of fixing the current conductor
position with respect to the monolithic CMOS
sensor, a fully integrated Hall-effect current
sensor is obtained, that is factory calibrated.
Inside the package, the magnetic flux density
generated by the current flow is sensed
differentially by two sets of Hall plates. As a result
the influence of external disturbing fields
originating from the dense power electronics
surrounding the IC is minimized in the fast analog
front-end. The residual signal is amplified to
provide a high-speed linear analog output voltage.
The close proximity of the Hall plates to the
current conductor ensures a high signal-to-noise
ratio and an accurate signal over temperature.
With this miniaturization, high voltage isolation
ratings are still maintained between the primary
and their opposing secondary side leads of the
package.
