ACEINNA Current Sensors use AMR Technology

February 21, 2019 Alix Paultre

ACEINNA’s new MCx1101 family of ±5A, ±20A, and ±50A AMR-based current sensors for industrial and power supply applications are fully integrated, bi-directional devices with high DC accuracy and dynamic range. For example, the ±20A version has a typical accuracy of ±0.6%, an offset of ±60mA, or ±0.3% of FSR (max) over temperature. Their 1.5MHz signal bandwidth, benchmark phase shift vs. frequency performance, and 4.8kV isolation suit high- and low-side sensing in fast current control loops, as well as fast-switching SiC and GaN based power stages.

Features include an output step response time of 0.3us, and an integrated overcurrent detection response time of 0.2us. The family includes ±50, ±20, and ±5A ranges, and is offered in both fixed gain (MCA1101) and ratiometric gain (MCR1101) versions. It is enclosed in an industry standard SOIC-16 package with a low impedance (0.9 milli-ohm) current path and is certified by UL/IEC/EN for isolated applications.
