Allegro Microsystems (ACS711KLCTR-25AB-T) Current Sensor, Overcurrent Fault

Current Sensor, Overcurrent Fault, 4 mA, 100 kHz, SOIC, 8 Pins, 3 V, 5.5 V Product Overview The ACS711KLCTR-25AB-T is a hall effect linear current sensor in 8 pin NSOIC package. This device provides economical and precise solutions for AC or DC current sensing in less than 100V isolation applications. It consists of a linear hall sensor circuit with copper conduction path located near surface of the die. Current flowing through this copper conduction path generates a magnetic field which is sensed by integrated hall IC and converted into a proportional voltage. Device accuracy is optimized through close proximity of magnetic signal to hall transducer. The ACS711 is optimized for low side current sensing applications. The terminals of conductive path are electrically isolated from sensor IC leads providing sufficient internal creepage and clearance dimensions for a low AC or DC working voltage applications. Typical sensitivity of 55mV/A Optimized accuracy range (IP) of ±25A No external sense resistor required, single package solution 1.2mohm internal conductor resistance Reduced power loss Economical low and high side current sensing Output voltage proportional to AC or DC currents Single supply operation from 3V to 5.5V 100KHz bandwidth Operating ambient temperature range from -40°C to 125°C Applications Sensing & Instrumentation, Audio, Communications & Networking, Consumer Electronics, Safety, Motor Drive & Control Product Information Quiescent Current: 4mA Bandwidth: 100kHz Sensor Case Style: SOIC No. of Pins: 8Pins Supply Voltage Min: 3V Supply Voltage Max: 5.5V Operating Temperature Min: -40°C Operating Temperature Max: 125°C MSL: MSL 2 - 1 year
