MLX91230 SMART IVT BATTERY SENSOR HALL-BASED DC CURRENT SENSING WITH UNPRECEDENTED ACCURACY

PublishTime：2023-09-26

●The MLX91230 is the first smart Hall-based current sensor of a Gen 3 portfolio. With a measurement of three physical quantities (current, voltage and temperature) and a dedicated 32 KB Flash memory on a single IC, this ASIL compliant product is ideal for safety applications. With its diagnostics the MLX91230 is removing an important part of the burden from the integrator in developing all the safety mechanisms. Boosting accuracy of Hall-effect DC current sensing, the MLX91230 comes with 0.5% accuracy over temperature (-40°C to 125°C) for a 1% lifetime drift all-in. The MCU enables automatic gain control to cover higher dynamic ranges, and the on-board flash memory supports custom software and extensive compensation of system imperfections. Supplied with a regulated 5V or directly connected to the 12V battery, the MLX91230 in SOIC8 outputs measurements and diagnostics either on LIN bus or via UART.
