Introduction

The MCA1101 products are ±5A, ±20A, ±50A fully integrated bi-directional analog output current sensors that deliver both high accuracy and high bandwidth. ACEINNA’s state-of-theart Anisotropic Magneto Resistive (AMR) sensor technology provides inherently low noise, excellent linearity and repeatability. A fully isolated current path is provided by a low resistance copper conductor integrated into the package making it suitable for both high-side and low side bi-directional current sensing. The high bandwidth of 1.5MHz (3dB) and low phase delay makes it ideal for current sense feedback loops in motor control, inverters, uninterruptible power supplies, battery management, power factor correction, high voltage distribution bus converters and power supply applications, including those with fast switching wide-bandgap SiC and GaN based power stages. These devices are factory-calibrated to achieve low offset error and provide a precise analog voltage output that is linearly proportional to the conduction current (AC or DC) with sensitivity (mV/A) compatible with A/D converters and analog control loops in power systems. The AMR sensor device structure is designed to eliminate sensitivity to stray and common mode magnetic fields. Due to the inherently low output noise of ACEINNA’s sensor technology, additional filtering is not required to reduce noise that reduces accuracy at low-level currents in systems with dynamic load profiles. The MCA1101 products in SOIC-16 package are simple to use with no or minimal external components (other than decoupling capacitor) enabling fast design, supports high isolation and are UL/IEC/EN60950-1 certified.
