Current Sensor 100A 1 Channel Hall Effect, Open Loop Bidirectional 5-CB Formed Leads,
PFF
The ACS758LCB-100B-PFF-T is a fully integrated Hall-effect current sensor IC from Allegro MicroSystems, designed for accurate and electrically isolated measurement of both AC and DC currents up to ±100 A. It incorporates a precision Hall sensing element positioned near a low-resistance copper current conductor, producing an analog output voltage proportional to the sensed current. The device offers galvanic isolation between the current path and signal pins, making it ideal for high-voltage and high-current applications such as motor drives, power supplies, inverters, battery management systems, and overcurrent protection circuits.
