current sensor ic Allegro ACS37010LLZATR030B3 with aec q100 grade 0 and 6 pin soic package design
Product Overview
The ACS37010 and ACS37012 are fully integrated, highly accurate current sensor ICs designed for robust current measurement in a compact SOIC LZ package. Featuring a low 0.68 m internal conductor resistance for minimal power dissipation, these sensors offer factory-trimmed precision without customer programming. They provide high isolation (3500 VRMS withstand voltage) and differential sensing to reject common-mode magnetic fields. The ACS37010 provides a fast 1.3 s analog output with a VREF pin for noisy environments, while the ACS37012 offers a fast logic alert fault output for overcurrent detection and system protection. These AEC-Q100 Grade 0 automotive-qualified devices are ideal for applications requiring precise and reliable current monitoring.
