Application Examples Programmable high speed current sensor Inverter applications in HEV and EV Programmable linear transfer characteristic BLDC motor current monitoring Selectable analog ratiometric output AC/DC converters Measurement range from 15 to 450mT Over current detection circuit Single die VA package RoHS compliant Wideband: DC to 250kHz Short response time 2sec Lead free component, suitable for lead free soldering profile 260C (target), MSL1 AEC-Q100 Automotive Qualified Figure 1: Typical Current Sensing Application 3. General Description The MLX91209 is a monolithic programmable Hall where a very fast response is required, such as inverter applications. sensor IC featuring the planar Hall technology, In a typical application, the sensor is used in which is sensitive to the flux density applied combination with a ring shaped soft ferromagnetic orthogonally to the IC surface. The sensor provides core. The Hall IC is placed in a small air gap and the an output signal proportional to the applied magnetic flux density and is preferably suited for current conductor is passed through the inner part of the ferromagnetic ring. The ring concentrates and current measurement. The transfer characteristic of amplifies the magnetic flux on the Hall sensor IC, the MLX91209 is programmable (offset, gain). The which generates an output voltage proportional to linear analog output is designed for applications the current flowing in the conductor. 4.
