MELEXIS MLX91216 XHF extra high-field current sensor extends the ease and accuracy of firm’s IMC-Hall technology into high-current measurement for emerging automotive applications. Capable of measuring current to beyond 2000A, device is suitable for redundant monitoring of battery-management systems (BMS), over-current detection in smart fuses, and measuring phase currents in traction inverters and boost/recuperation inverters. With user-programmable filtering to adjust resolution, response time, and bandwidth for optimum signal-to-noise ratio, the sensor features built-in diagnostics, including broken-wire detection. The SOIC8 surface-mount device contains firm’s patented Integrated Magnetic Concentrator (IMC) that enables accurate contact-free measurement of busbar current in combination with a simple U-shape magnetic shield. When mounted on a PCB, the sensor is positioned over the busbar, within the shield, allowing easier assembly than conventional Hall sensors.
