Melexis announced its MLX91206 Series for contact-less current sensing in renewable energy, hybrid electric vehicle (HEV) and electric vehicle (EV) applications. The customer programmable monolithic sensor IC, featuring Triaxis Hall technology, enables the user to construct small, economical current sensor solutions with fast response times. The chip directly monitors the current flowing in an external conductor such as a bus bar or PCB track. The MLX91206 consists of a CMOS Hall integrated circuit with a thin ferromagnetic layer structured on its surface. The integrated ferromagnetic (IMC) layer is used as a magnetic flux concentrator providing a high magnetic gain which significantly increases the signal to noise ratio of the sensor. The sensor is appropriate for DC and/or AC current measurements up to 90 kHz with ohmic isolation, very low insertion loss, fast response time, small package size and low assembly cost requirements. It features over voltage and reverse voltage protection including broken track diagnostics and can be used as a “stand-alone” current sensor connected directly to a cable.
