ACS758LCB-100U-PFF-T

The ACS758LCB-100U-PFF-T is a thermally enhanced, fully integrated, hall effect based linear current sensor IC in 5 pin CB package with PFF lead form. It provides economical and precise solutions for AC or DC current sensing. It consists of precision, low offset linear hall circuit with copper conduction path located near die. The current flowing through this copper conduction path generates a magnetic field which hall IC converts into a proportional voltage. Device accuracy is optimized through close proximity of magnetic signal to hall transducer. A precise and proportional output voltage is provided by low offset, chopper stabilized BiCMOS hall IC which is programmed for accuracy at 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 and high voltage applications. This device is CB, UL E316429, CE and TUV approved.
