ACS758KCB-150B-PFF-T

The ACS758KCB-150B-PFF-T is a hall effect-based linear Current Sensor IC provides economical and precise solutions for AC or DC current sensing. The thermally enhanced, fully integrated device consists of a precision, low-offset linear hall circuit with a copper conduction path located near the die. Applied current flowing through this copper conduction path generates a magnetic field which the hall IC converts into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the hall transducer. A precise, proportional output voltage is provided by the low-offset, chopper-stabilized BiCMOS hall IC, which is programmed for accuracy at the factory. High level immunity to current conductor dV/dt and stray electric fields, offered by Allegro proprietary integrated shield technology, provides low output voltage ripple and low offset drift in high-side, high voltage applications.
