Hall effect integrated circuit current sensor MLX91211

PCBDCAC

The MLX91211 is a second-generation medium-speed current sensor that senses the magnetic field generated by the current flowing through a conductor, be it a cable, a bus bar or a PCB trace in a contactless way. The MLX91211 is a second-generation medium-speed current sensor that senses the magnetic field generated by the current flowing through a conductor, be it a cable, a bus bar or a PCB trace. To minimize the susceptibility to external magnetic fields and maximizing the concentration of the magnetic field generated by the current flow, the sensor is typically placed inside a ferromagnetic core. MLX91211 - 40 kHz conventional Hall current sensor IC The sensor has an analog output ratiometric to its supply voltage (which can be in the range of 3.135 V to 5.5 V). The MLX91211 contains a voltage regulator for stable internal supply and optimum performances. The output is proportional to the sensed magnetic field perpendicular to the package surface. The device is pre-programmed with different sensitivity settings as a function of different current sensing ranges and features a factory-calibrated quiescent output voltage at 50% of the supply voltage. The sensor is optimized for cost-sensitive applications, and comes in 2 variants: - the ABT version with multi-temperature trimming of the sensitivity, and high accuracy - the ABA version with default trimming, and standard accuracy Features and benefits Linear Hall sensor optimized for AC and DC current sensing applications Supply voltage in the range of 3.135 V to 5.5 V Analog ratiometric output voltage Factory trimmed magnetic sensitivity and offset Medium speed sensing DC to 40 kHz bandwidth
