High Accuracy Current Sensor IC with 1.5MHz 3dB Bandwidth and Isolation 5A, 20A, 50A, 3.3V, Ratiometric MCR1101-xx-3 FEATURES DESCRIPTION AMR based integrated current sensor The MCR1101 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 (MCR1101-20-3) art Anisotropic Magneto Resistive (AMR) sensor technology 2.0% max error over temperature (MCR1101-20-3) 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 Overcurrent fault detection delay makes it ideal for current sense feedback loops in motor SOIC-16 package (RoHS/REACH compliant) control, inverters, uninterruptible power supplies, battery -40 to +105C Operating Temperature Range management, power factor correction, high voltage distribution bus converters and power supply applications, UL/IEC/EN60950-1 Certified including those with fast switching wide-bandgap SiC and 4.8 kV Dielectric Strength Voltage GaN based power stages. 1097 VRMS Basic Isolation Voltage 400 VRMS Reinforced Isolation Voltage 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 APPLICATIONS sensitivity (mV/A) compatible with A/D converters and analog control loops in power systems. The AMR sensor device Server, Telecom, & Industrial Power Supplies structure is designed to eliminate sensitivity to stray and Power Aggregation, Over-Current Protection common mode magnetic fields. Dynamic Current Sensing in Feedback Loops PFC and Inverter Control Due to the inherently low output noise of ACEINNAs sensor Motor Control Loops & Protection technology, additional filtering is not required to reduce noise Automation, Robotics, Servo Systems that reduces accuracy at low-level currents in systems with Automotive & EV Power Systems dynamic load profiles. Solar Inverters and Optimizers The MCR1101 products in SOIC-16 package are simple to Grid-Tie and Storage Current Monitoring use with no or minimal external components (other than MPPT Circuit Current Monitoring decoupling capacitor), supports high isolation and are Central Inverter Current Monitoring UL/IEC/EN60950-1 certified.
