ACHS-7195-500E

ACHS-7195-500E is a fully integrated hall-effect-based isolated linear current sensor designed for AC or DC current sensing in industrial, commercial, and communications systems. Inside each ACHS-719x IC is a precise, low-offset, linear hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field that the differential Hall sensors convert into a proportional voltage. Device accuracy is optimized across the operating ambient temperature through the close proximity of the magnetic signal to the Hall sensors. A precise, proportional voltage is provided by the low-offset, chopper-stabilized CMOS Hall IC, which is programmed for accuracy after packaging. Applications include low-power inverter current sensing, eBikes, motor phase and rail current sensing, solar inverters, chargers and converters, switching power supplies.
