MLX91221 Current Sensors

Melexis MLX91221 Current Sensors operate on a 3.3V voltage supply and are robust against external magnetic fields. These 0A to 50A integrated Hall effect sensors provide dual overcurrent detection (OCD) on-chip with a separated output, reducing the need for external comparators for overcurrent protection. They sense the current flowing through the lead frame of their SOIC package, minimizing the thermal losses encountered with more standard solutions. The all-in-one MLX91221 sensors offer a small footprint, low impedance, high bandwidth, and isolation. Melexis MLX91221 Current Sensors feature high-speed sensing with a 2μs response time and DC to 300kHz bandwidth. The lead-free components are suitable for lead-free soldering profiles up to +260°C, MSL3. Applications include AC and DC chargers, electric drives, DC-DC converters, solar, power supplies, and demand/load control.
