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.

body package, RoHS compliant
Lead free component, suitable for lead
free soldering profile up to 260°C, MSL3
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.
Rated voltage isolation

2.1kVRMS for SOIC-8
2.5kVrms for SOIC-16
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.
