MLX91210KDF-CAS-101-SP

Melexis MLX91210 Integrated Current Sensor IC senses the current flowing through the leadframe of the SOIC package. The current conductor exhibits low power dissipation (0.7 - 0.8m). The sensor uses a fixed current conductor position with respect to the monolithic CMOS sensor to obtain a fully integrated, factory calibrated, Hall-effect current sensor. Running off a 5V supply, MLX91210 ICs have current sensitivity levels down to 26.7mV/A and support linear current measurement ranges that span as far as �75A corresponding to 30Arms current.Available in SO8 and SO16 package formats, these fully integrated Hall-effect current sensors have extremely low resistive losses (0.8m for the SO8 and 0.7m for the SO16) and provide high voltage isolation ratings (2.1kVrms and 2.5kVrms respectively), as well as accelerated responsiveness (within just 5us). The sensor output of each IC is factory-calibrated for a specific current range and compensated for optimal stability in relation to temperature and over the course of its working lifespan, so that long term accuracy is maintained.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 MLX91210 ensures a high signal-to-noise ratio and an accurate signal over temperature due to the close proximity of the Hall plates to the current conductor. High voltage isolation ratings are maintained between the primary and their opposing secondary side leads of the package with the sensor's miniaturization.
