High Accuracy Current Sensor IC with 1.5MHz 3dB Bandwidth and Isolation 5A, 20A, 50A, 5V, Ratiometric MCR1101-xx-5 FEATURES DESCRIPTION AMR based integrated current sensor The MCR1101 products are 5A, 20A, 50A fully Superior Range & Accuracy integrated bi-directional analog output current sensors that 0.6% typical total error 25C (MCR1101-20-5) deliver both high accuracy and high bandwidth. ACEINNAs 2.0% max error over temperature (MCR1101-20-5) state-of-the-art Anisotropic Magneto Resistive (AMR) sensor Superior Frequency Response technology provides inherently low noise, excellent linearity 1.5 MHz (typical 3dB BW) and repeatability. 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 5V Supply Operation suitable for both high-side and low side bi-directional current Low power consumption (6.5mA typical) sensing. The high bandwidth of 1.5MHz (3dB) and low Overcurrent fault detection phase delay makes it ideal for current sense feedback loops SOIC-16 package (RoHS/REACH compliant) in motor control, inverters, uninterruptible power supplies, -40 to +105C Operating Temperature Range battery management, power factor correction, high voltage UL/IEC/EN60950-1 Certified distribution bus converters and power supply applications, 4.8 kV Dielectric Strength Voltage including those with fast switching wide-bandgap SiC and 1097 VRMS Basic Isolation Voltage GaN based power stages. 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) APPLICATIONS with sensitivity (mV/A) compatible with A/D converters and Server, Telecom, & Industrial PWR Supplies analog control loops in power systems. The AMR sensor Power Aggregation, Over-Current Protection device structure is designed to eliminate sensitivity to stray Dynamic Current Sensing in Feedback Loops and common mode magnetic fields. PFC and Inverter Control Motor Control Loops & Protection Due to the inherently low output noise of ACEINNAs sensor Automation, Robotics, Servo Systems technology, additional filtering is not required to reduce Automotive & EV Power Systems noise that reduces accuracy at low-level currents in systems Solar Inverters and Optimizers with dynamic load profiles. Grid-Tie and Storage Current Monitoring The MCR1101 products in SOIC-16 package are simple to MPPT Circuit Current Monitoring use with no or minimal external components (other than Central Inverter Current Monitoring decoupling capacitor), supports high isolation and are Consumer UL/IEC/EN60950-1 certified.
