Allegro Microsystems (ACS713ELCTR-20A-T) Current Sensor, Voltage Isolation

Current Sensor, Voltage Isolation, 80 kHz, SOIC, 8 Pins, 4.5 V, 5 VProduct OverviewThe ACS713ELCTR-20A-T is a fully integrated, hall effect-based linear CurrentSensor IC. It provides economical and precise solutions. The device packageallows for easy implementation by the customer. The device consists of aprecise, low-offset, linear Hall sensor circuit with a copper conduction pathlocated near the surface of the die. Applied current flowing through this copperconduction path generates a magnetic field which is sensed by the integratedHall IC and converted into a proportional voltage. Device accuracy is optimizedthrough the close proximity of the magnetic signal to the Hall transducer. Aprecise, proportional voltage is provided by the low-offset, chopper-stabilizedBecomes Hall IC, which is programmed for accuracy after packaging. The output ofthe device has a positive slope (>VIOUT(Q)) when an increasing current flowsthrough the primary copper conduction path (from pins 1 and 2, to pins 3 and 4),which is the path used for current sensing.Low-noise Analogue Signal PathDevice Bandwidth is Set Via New Filter Pin5µs Output Rise Time in Response to Step Input Current1.5% at TA = 25°C Total Output Error1.2mR Internal Conductor Resistance2.1kVrms Minimum Isolation Voltage from Pins 1-4 to Pins 5-8185mV/A Output SensitivityOutput Voltage Proportional to DC CurrentsFactory-trimmed for AccuracyExtremely Stable Output Offset VoltageNearly Zero Magnetic HysteresisRatiometric Output from Supply VoltageApplicationsSensing & Instrumentation, Industrial, Commercial, Communications & Networking,Motor Drive & Control, Power Management, SafetyProduct InformationBandwidth: 80kHzSensor Case Style: SOICNo. of Pins: 8PinsSupply Voltage Min: 4.5VSupply Voltage Max: 5VOperating Temperature Min: -40°COperating Temperature Max: 85°CMSL: MSL 2 - 1 year
