MCR1101-20-3

The MCR1101 products are ±5A, ±20A, ±50A fully integrated
bi-directional analog output current sensors that deliver both
high accuracy and high bandwidth. ACEINNA’s state-of-theart Anisotropic Magneto Resistive (AMR) sensor technology
provides inherently low noise, excellent linearity and
repeatability.
A fully isolated current path is provided by a low resistance
copper conductor integrated into the package making it
suitable for both high-side and low side bi-directional current
sensing. The high bandwidth of 1.5MHz (3dB) and low phase
delay makes it ideal for current sense feedback loops in motor
control, inverters, uninterruptible power supplies, battery
management, power factor correction, high voltage
distribution bus converters and power supply applications,
including those with fast switching wide-bandgap SiC and
GaN based power stages.
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
sensitivity (mV/A) compatible with A/D converters and analog
control loops in power systems. The AMR sensor device
structure is designed to eliminate sensitivity to stray and
common mode magnetic fields.
Due to the inherently low output noise of ACEINNA’s sensor
technology, additional filtering is not required to reduce noise
that reduces accuracy at low-level currents in systems with
dynamic load profiles.
The MCR1101 products in SOIC-16 package are simple to
use with no or minimal external components (other than
decoupling capacitor), supports high isolation and are
UL/IEC/EN60950-1 certified.
