Allegro MicroSystems ACS720
The ACS720 is a high accuracy Hall-effect-based current sensor IC with multiple programmable fault levels intended for industrial and consumer applications with a focus on motor control and power inverter stage applications. The ACS720 works off of a single 5 V supply while maintaining an output voltage swing from 0 to 3 V, with a stable zero current output of 1.5 V. This allows the ACS720 to operate off of a 5 V supply while having an output which is compatible with typical 3.3 V ADCs found on many MCUs.| Part No. | ACS720 |

FEATURES AND BENEFITS
● Differential current sensing cancels common mode fields, simplifying PCB layout● Two user-settable faults for fast short-circuit protection and slower overcurrent detection
● Industry-leading noise performance with greatly improved bandwidth through proprietary amplifier and filter design techniques
● Patented integrated digital temperature compensation circuitry allows high accuracy over temperature in an open loop sensor
● 1.0 mΩ primary conductor resistance for low power loss and high inrush current-withstanding capability
● Small footprint, low-profile SOIC16 package suitable for space-constrained applications
● Integrated shield virtually eliminates capacitive coupling from current conductor to die due to high dV/dt voltage transients
● 5 V single supply operation with 0-3 V output swing
● Output voltage proportional to AC or DC current
● Factory-trimmed sensitivity and quiescent output voltage for improved accuracy
● 3600 Vrms Dielectric Strength certifie...
