MLX91210 Integrated Current Sensor IC Datasheet Features and Benefits Applications Factory trimmed AC and DC current sensor Household/Appliance Smart Metering Analog ratiometric output voltage Electric Motor Control Combining sensing element, signal Demand Response Load Control conditioning & isolation in small footprint Servers / Motherboard monitoring and low profile SOIC package Switched Mode Power Supplies No application programming required High speed sensing DC to 100kHz bandwidth Description 5s response time The MLX91210 is an Integrated Current Sensor Robust against external magnetic fields that senses the current flowing through the leadframe of the SOIC package. The current No magnetic hysteresis conductor exhibits low power dissipation (0.7 - Low ohmic losses of integrated conductor 0.8m). By virtue of fixing the current conductor 0.8m SOIC-8 / 0.7m SOIC-16 position with respect to the monolithic CMOS sensor, a fully integrated Hall-effect current SOIC-8 narrow body and SOIC-16 wide sensor is obtained, that is factory calibrated. body package, RoHS compliant Lead free component, suitable for lead Inside the package, the magnetic flux density free soldering profile up to 260C, MSL3 generated by the current flow is sensed differentially by two sets of Hall plates. As a result Rated voltage isolation the influence of external disturbing fields 2.5kV for SOIC-8 originating from the dense power electronics RMS surrounding the IC is minimized in the fast analog 2.5kV for SOIC-16 RMS 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 SOIC-8 SOIC-16 ratings are still maintained between the primary and their opposing secondary side leads of the package.
