High-Speed Isolated Integrated Hall Current Sensor
MLX91220 & MLX91221
The MLX91220 series defines Melexis’ next-generation high-speed isolated integrated current sensor. The Hall-effect based current sensors are qualified for use in a wide range of automotive and industrial applications, such as on-board chargers (OBC), DC/DC converters, power supplies, and small electric drives.
By combining sensing elements, signal conditioning and voltage isolation into a small footprint surface mount package, it is de facto the easiest all-in-one integrated current sensor. Two package variants are offered, with different creepage and clearance and rated isolation voltages.
With 300 kHz bandwidth, the MLX91220 and MLX91221 suit a variety of power conversion applications supporting current measurements lower than 50 A. The sensor is robust against shorter transients beyond 50 A.
The MLX91220 and MLX91221 differ only in the supply voltage at which they operate:
- MLX91220: operates on 5 V supply
- MLX91221: operates on 3.3 V supply
