ACS711 Hall Effect Linear Current Sensor with Overcurrent Fault Output for 100 V Isolation Applications Features and Benefits Description ? No external sense resistor required; single package solution The Allegro? ACS711 provides economical and precise ? Reduced Power Loss: solutions for AC or DC current sensing in 100 V audio, ? 0.6 mΩ internal conductor resistance on EX package communications systems, and white goods. The device package ? 1.2 mΩ internal conductor resistance on LC package allows for easy implementation by the customer. Typical ? Economical low- and high-side current sensing applications include circuit protection, current monitoring, ? Output voltage proportional to AC or DC currents and motor and inverter control. ? ±12.5 A and ±25 A full scale sensing ranges on LC package ? ±15.5 A and ±31 A full scale sensing ranges on EX package The device consists of a linear Hall sensor circuit with a copper ? Overcurrent Fˉ Aˉ ˉ Uˉ ˉ Lˉ ˉ Tˉ ˉ trips and latches at 100% of full-scale current conduction path located near the surface of the die. Applied ? Low-noise analog signal path current flowing through this copper conduction path generates ? 100 kHz bandwidth a magnetic field which is sensed by the integrated Hall IC ? Small footprint, low-profile SOIC8 and QFN packages and converted into a proportional voltage. Device accuracy is ? 3.0 to 5.5 V, single supply operation optimized through the close proximity of the magnetic signal ? Integrated electrostatic shield for output stability to the Hall transducer. ? Factory-trimmed for accuracy ? Extremely stable output offset voltage
