MLX91230 - Melexis

MLX91230 Smart IVT Sensor

The MLX91230 is the first Melexis smart Hall-based current sensor and is part of Gen3 portfolio. With a measurement capability of three physical quantities: Current, Voltage and Temperature, Overcurrent detection alongside a dedicated 32 KB Flash memory on a single IC, this ASIL-compliant chip is ideal for safety applications. With its diagnostics, the MLX91.
