MLX91208 IMC-Hall Current Sensor 1. Features and Benefits 3. Description The MLX91208 is a monolithic sensor IC featuring the IMC- IMC-Hall Technology Hall technology. Conventional planar Hall technology is Very high sensitivity due to Integrated only sensitive to the flux density applied orthogonally to the Magnetic Concentrator (IMC-Hall) IC surface. The IMC-Hall current sensor is sensitive to the flux density applied parallel to the IC surface. This is Programmable high speed current sensor IC obtained through an Integrated Magneto-Concentrator Wideband: DC to 250kHz (IMC-Hall) which is deposited on the CMOS die (as an additional back-end step). The IMC-Hall technology is Short response time 3us automotive qualified. Programmable linear transfer characteristic The product is a single chip Hall sensor which provides an Selectable Analog ratiometric output output signal proportional to the flux density applied horizontally and is therefore suitable for current SOIC8 package RoHS compliant measurement. It is ideally suited as an open loop current Lead free component, suitable for lead free sensor for PCB or bus bar mounting. It features small size soldering profile 260C (target), MSL3 application design and a simple construction for various current ranges from few Amperes up to 1000 Amperes. AEC-Q100 Automotive Qualified The transfer characteristic of the MLX91208 is programmable in terms of offset, gain or temperature 2. Application Examples compensation. The linear analog output is designed for Inverter HEV and EV applications where a very fast response is required, such as inverter applications.
