描述 Description

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.

For minimizing 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.

The sensor has an analog output ratiometric with

varying supply voltage. The MLX91211 contains a

voltage regulator for stable internal supply. The

output is proportional to said magnetic field

perpendicular to the package surface. The device

is offered at 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, and comes in 2

variants: the ABT version with multi-temperature

trimming of the sensitivity, and the standard

accuracy ABA version which has default trimming

and wider specs.
