MLX91220 Current Sensors

Melexis MLX91220 Current Sensors operate on a 5V voltage supply and provide high common-mode field rejection through differential sensing. They sense the current flowing through the lead frame of their SOIC package, minimizing the thermal losses encountered with more standard solutions. These 0A to 50A integrated Hall effect sensors feature dual overcurrent detection (OCD) on-chip with a separated output, reducing the need for external comparators for overcurrent protection. The all-in-one MLX91220 sensors offer an ideal balance of a small footprint, low impedance, high bandwidth, and isolation. Melexis MLX91220 Current Sensors provide high-speed sensing with a DC to 300kHz bandwidth and 2μs response time. Typical applications include AC and DC chargers, electric drives, DC-DC converters, solar, power supplies, and demand/load control.
