                                                                                                  ACS709LLFTR-35BB-T is an Allegro™ high-bandwidth, fast fault response current sensor IC in thermally enhanced package. It provides economical and precise means for current sensing applications in industrial, automotive, commercial, communications system. It is offered in a small footprint surface mount package that allows easy implementation in customer applications. It consists of precision linear hall sensor integrated circuit with copper conduction path located near the surface of the silicon die. Applied current flows through the copper conduction path, the analog output voltage from the Hall sensor IC linearly tracks the magnetic field generated by the applied current. The accuracy of maximized with this patented packaging configuration because the Hall element is situated in extremely close proximity to the current to be measured. Application includes motor control and protection, load management and overcurrent detection, power conversion and battery monitoring / UPS systems.
