The ±20A version has a typical accuracy of ±0.6% and is guaranteed to achieve an accuracy of ±2.0% (max) at 85°C.
The new current sensors also guarantee an offset of ±60mA, or ±0.3% of FSR (max) over temperature, which means that high accuracy can be achieved over a roughly 10:1 range of currents. This is a roughly a ten-fold improvement in dynamic range versus leading Hall-sensor-based devices. These devices deliver a unique combination of high accuracy, 1.5MHz signal bandwidth with industry benchmark phase shift versus frequency and 4.8kV isolation making them suitable for high- and low-side sensing in fast current control loops for high performance power supplies, inverters and motor control applications. Output step response time is 0.3us. The MCx1101 also provides an integrated over current detection flag to help implement over current protection required in modern power systems, with detection response time of 0.2us. The family is offered in both fixed gain (MCA1101) and ratiometric gain (MCR1101) versions. It comes packaged 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.
