Product description
The MLX91218 is a high-speed high-accuracy IMC-Hall® current sensor simplifying module designs with a dual OverCurrent Detection (OCD) functionality, a flexible supply 3.3V/5V and an improved SNR. With the IMC-Hall® technology - using a flexible U-shield for crosstalk immunity - currents can be measured in the ranges of 200A to 2000A.
The MLX91218 is a monolithic Hall-effect sensor based on the IMC-Hall® technology. The sensor provides an analog output voltage proportional to the applied magnetic flux density parallel to the IC surface.
The transfer characteristic of the MLX91218 is factory trimmed over temperature, and is programmable (offset, sensitivity, filtering, internal overcurrent threshold) during end-of-line customer calibration.
With its 400kHz bandwidth and fast response time, it is particularly adapted for high speed applications such as motor control, inverters and converters where fast response time, due to fast switching, is required.
Coming in a SOIC8 package, it includes a second OCD. To be noted that the on-chip overcurrent detection feature allows for board space and cost savings, by reporting an OCD event with active low open-drain output, that can be set within or outside the output linear sensing range.
