ACEINNA’s MCx1101 AMR current sensors now support 3.3V applications, making them suitable for microprocessor and ADC-based power systems. The ±50, ±20, and ±5A bi-directional current sensors deliver high DC accuracy and dynamic range in both fixed gain and ratiometric gain versions.

The MCx1101 current sensors guarantee an offset of ±60mA (±0.3 percent Full Scale Range (FSR)) over temperature, enabling accuracy over a 10:1 range of currents. The ±20A version, for instance, has a typical accuracy of ±0.6 percent with guaranteed accuracies of ±2.0 percent at 85°C.

Other features include:

• 1.5 MHz signal bandwidth
• 0.3 µs output step response
• 4.8kV isolation
• Integrated overcurrent detection flag with 0.2 µs response time

MCx1101 devices are implemented in a SOIC-16 package with 0.9 mΩ impedance current path. They are available now in volume quantities.
