Allegro MicroSystems Inc. High Sensitivity, Gmr-Based Current Sensor IC ACS70331EOLCTR-2P5B3

Description
The ACS70331 is Allegro's first integrated, high sensitivity, current sensor IC for <5 A current sensing applications. It incorporates giant magneto-resistive (GMR) technology that is 25 times more sensitive than traditional Hall-effect sensors to sense the magnetic field generated by the current flowing through the low resistance, integrated primary conductor. The analog output provides a low noise high-speed signal, which is proportional to the current flowing through the primary. The response time of the part is typically 535 ns. The ACS70331 is offered in four factory-programmed sensitivity and offset levels to optimize performance over the desired current measurement range. The differential configuration of the GMR elements, relative to the integrated current conductor, provides significant rejection of stray magnetic fields, resulting in stable operation even in magnetically noisy environments. The ACS70331 operates from a single 3.3 V power supply and is qualified over the full commercial temperature range of –40°C to 85°C. It is offered in a low-profile space-saving surface mount QFN and SOIC packages.
