Allegro Microsystems (ACS712ELCTR-30A-T) Linear Current Sensor

Linear Current Sensor, Hall Effect, 30A Sensing Current, SOIC-8 Product Overview The ACS712ELCTR-30A-T is a fully integrated, hall effect based linear current sensor IC in 8 pin SOIC package. It provides economical and precise solutions. The device package allows for easy implementation by the customer. The device consists of a precise, low-offset, linear hall sensor circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. A precise, proportional voltage is provided by the low-offset, chopper-stabilized Becomes Hall IC which is programmed for accuracy after packaging. Low noise analogue signal path Device bandwidth is set via new filter pin 5µs output rise time in response to step input current 1.5% at TA = 25°C total output error 1.2mohm internal conductor resistance 2.1KVrms minimum isolation voltage from pins 1-4 to pins 5-8 66mV/A output sensitivity Output voltage proportional to AC or DC currents Factory-trimmed for accuracy Extremely stable output offset voltage Nearly Zero Magnetic Hysteresis Ratiometric Output from Supply Voltage Applications Sensing & Instrumentation, Industrial, Commercial, Communications & Networking, Motor Drive & Control, Power Management, Safety Product Information Quiescent Current: 10mA Bandwidth: 80kHz Sensor Case Style: SOIC No. of Pins: 8Pins Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V Operating Temperature Min: -40°C Operating Temperature Max: 85°C
