Product Overview
The ACS37010 and ACS37012 are fully integrated current sensor ICs designed for accurate current sensing in a compact SOIC LZ package. Featuring a low 0.68 m primary conductor resistance for minimal power dissipation, these devices offer factory-trimmed high accuracy without customer programming. They provide excellent magnetic isolation and differential sensing to reject common-mode fields. The ACS37010 offers a fast 1.3 s response time with an analog output and VREF pin for noisy environments, while the ACS37012 provides a fast logic alert fault output for overcurrent and short-circuit detection. Both devices offer 3500 VRMS of isolation and are AEC-Q100 Grade 0 automotive qualified. Ideal for applications requiring precise current monitoring and system protection.
