Broadcom ACHS-719x family hall effect current sensors
The ACHS-719x product series is a fully integrated Hall Effect-based isolated linear current sensor device family designed for AC or DC current sensing
The ACHS-719x product series is a fully integrated Hall Effect-based isolated linear current sensor device family designed for AC or DC current sensing in industrial, commercial, and communications systems. The family consists of products with a sensing current ranging from ±10 A to ±50 A. The devices offer a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current generates a magnetic field that the Hall IC converts into a proportional voltage. Device accuracy is optimized through the use of differential Hall transducers.

Device accuracy is optimized through the close proximity of the magnetic signal to the differential Hall transducers. A precise, proportional voltage is provided by the low-offset, chopper-stabilized CMOS Hall IC, which is programmed for accuracy after packaging. The output of the device has a positive slope (> VOUT(Q)) when an increasing current flows through the primary copper conduction path (from pins 1 - 2 to pins 3 - 4), which is the path used for current sampling.
