The ACS709LLFTR-35BB-T is a high bandwidth fast fault response Current Sensor IC provides economical and precise means for current sensing applications. The ACS709 sensor consists of a precision linear hall sensor integrated circuit with a copper conduction path located near the surface of the silicon die. Applied current flows through the copper conduction path and the analogue output voltage from the hall sensor IC linearly tracks the magnetic field generated by the applied current. High level immunity to current conductor DV/DT and stray electric fields, offered by proprietary integrated shield technology, provides low output ripple and low offset drift in high-side applications.
