High Accuracy Current Sensor IC with 1.5MHz 3dB Bandwidth and Isolation 5A, 20A, 50A, 3.3V, Fixed Gain MCA1101-xx-3 FEATURES DESCRIPTION AMR based integrated current sensor The MCA1101 products are 5A, 20A, 50A fully integrated bi-directional analog output current sensors that deliver both Superior Range & Accuracy high accuracy and high bandwidth. ACEINNAs state-of-the- 0.6% typical total error 25C (MCA1101-20-3) art Anisotropic Magneto Resistive (AMR) sensor technology 2.0% max error over temperature (MCA1101-20-3) provides inherently low noise, excellent linearity and Superior Frequency Response repeatability. 1.5 MHz (typical 3dB BW) Fast output response time (300ns typical) A fully isolated current path is provided by a low resistance Low Primary Resistance (0.9 m) copper conductor integrated into the package making it Single 3.3V Supply Operation suitable for both high-side and low side bi-directional current Low power consumption (4.5mA typical) sensing. The high bandwidth of 1.5MHz (3dB) and low phase Zero-Current Reference Pin (Vref) delay makes it ideal for current sense feedback loops in motor Overcurrent fault detection control, inverters, uninterruptible power supplies, battery SOIC-16 package (RoHS/REACH compliant) management, power factor correction, high voltage distribution bus converters and power supply applications, -40 to +105C Operating Temperature Range including those with fast switching wide-bandgap SiC and UL/IEC/EN60950-1 Certified GaN based power stages. 4.8 kV Dielectric Strength Voltage 1097 VRMS Basic Isolation Voltage These devices are factory-calibrated to achieve low offset 400 VRMS Reinforced Isolation Voltage 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 APPLICATIONS structure is designed to eliminate sensitivity to stray and Server, Telecom, & Industrial Power Supplies common mode magnetic fields. Power Aggregation, Over-Current Protection Due to the inherently low output noise of ACEINNAs sensor Dynamic Current Sensing in Feedback Loops technology, additional filtering is not required to reduce noise PFC and Inverter Control that reduces accuracy at low-level currents in systems with Motor Control Loops & Protection dynamic load profiles. Automation, Robotics, Servo Systems Automotive & EV Power Systems The MCA1101 products in SOIC-16 package are simple to Solar Inverters and Optimizers use with no or minimal external components (other than Grid-Tie and Storage Current Monitoring decoupling capacitor) enabling fast design, supports high MPPT Circuit Current Monitoring isolation and are UL/IEC/EN60950-1 certified.
