MLX91220 Integrated Current Sensor IC Datasheet Features and Benefits Applications Factory trimmed AC and DC current sensor AC and DC Chargers Analog ratiometric or fixed output voltage Electric Drives Combining sensing element, signal DCDC converters conditioning & isolation in SOIC package Solar No application programming required Power Supplies High speed sensing Demand/Load control DC to 300kHz bandwidth Description 2s response time Robust against external magnetic fields The MLX91220 is an Isolated Integrated Current No magnetic hysteresis Sensor that senses the current flowing through the low impedant leadframe of the SOIC package. By Double overcurrent detection (SOIC-16) virtue of fixing the current conductor position with Low ohmic losses of integrated conductor respect to the monolithic CMOS sensor, a fully integrated Hall-effect current sensor is obtained, 0.9m SOIC-8 / 0.75m SOIC-16 that is factory calibrated. SOIC-8 narrow body and SOIC-16 wide body package, RoHS compliant Inside the package, the magnetic flux density generated by the current flow is sensed Lead free component, suitable for lead differentially by two sets of Hall plates. As a result free soldering profile up to 260C, MSL3 the influence of external disturbing fields is Rated voltage isolation minimized in the fast analog front-end. The residual signal is amplified to provide a high-speed 2.4kV for SOIC-8 RMS linear analog output voltage. 4.8kV for SOIC-16 RMS The close proximity of the Hall plates to the current conductor ensures a high signal-to-noise ratio and an accurate signal over temperature. Even with this miniaturization, high voltage isolation ratings are still maintained between the primary and the opposing secondary side.
