DESCRIPTION
The MCA1101 products are ± 5A, ± 20A, ± 50A, ± 65A fully integrated bi-directional analog output current sensor s that deliver both high accuracy and high bandwidth. ACEINNA’s state-of-the-art 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 int egrated into the package making it suitable for both high-side and low side bi-directional current sensing. The high bandwidth of 5.0MHz (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 MCA1101 products in SOIC -16 package are simple to use with no or minimal external components (other than decoupling capacitor ) enabling fast design, supports high isolation and are UL/IEC/EN62368-1 certified.

Document: 6020-1104-01 Rev J Page 11 of 16 AMR TECHNOLOGY Anisotropic magnetoresistance (AMR) makes use of a common material, Permalloy, to act as a magnetometer. Permalloy is an alloy containing roughly 80% nickel and 20% iron. The alloy’s resistance depends on the angle between the magnetization and the direction of current flow. In a magnetic fi eld, magnetization rotates toward the direction of the magnetic field and the rotation angle depends on the external field’s magnitude. Permalloy’s resistance decreases as the direction of magnetization rotates away from the direction in which current flows, and is lowest when the magnetization is perpendicular to the direction of current flow. The resistance changes roughly as the square of the cosine of the angle between the magnetization and the direction of current flow. Permalloy is deposited on a silicon wafer and patterned as a resistive strip. The film’s properties cause it to change resistance in the presence of a magnetic field. In a current sensor application, two of these resistors are connected in a Wheatstone bridge configuration to permit the measurement of the magnitude of the magnetic field produced by the current. AMR properties are well behaved when the film’s magnetic domains are aligned in the same direction. This configuration ensures high sensitivity, good repeatability, and minimal hysteresis. During fabrication, the film is deposited in a strong magnetic field that sets the preferred orientation, or “easy” axis, of the magnetization vector in the Permalloy resistors. AMR has better sensitivity than other methods and reasonably good temperature stability. The AMR sensor has sensitivity which is approximately a linear function of temperature. FUNCTIONAL DESCRIPTION Figure 2 provide block diagrams of the fixed gain. The AMR sensor monitors the magnetic field generated by the current flowing through the U shaped IP+/IP - package lead frame. The AMR sensor produces a voltage proportional to the magnetic field created by the positive or negative current in the IP+/IP - current loop while rejecting external magnetic interference. The sensor voltage is fed into a differential amplifier whose gain is temperature compensated. This is followed by an instrumentation amplifier ou tput stage that provides a voltage that indicates the current passing through the IP+/IP - pins. To provide both positive and negative current data the Vout output pin is referenced to the Vref output pin. The voltage on the Vref output is typically one half of the full scale positive and negative range of the Vout current sense output signal. With no current flowing in the IP+/IP - pins, the voltage on the Vout output will typically equal the voltage on the Vref output. Positive IP+/IP - current causes the vo ltage on Vout to increase relative to Vref while negative IP+/IP- current will cause it to decrease. GAIN The sensor resistors are biased by an internal 3.0V reference voltage and the voltage on the Vref output is 1.5V (typical). This arrangement provides a fixed gain and enhanced supply rejection. The Vout pin drives to approximately 2.8V at full positive current and 0.3V at full negative current. POWER UP / DOWN An under -voltage lockout circuit monitors the voltage on the VCC pin. If the VCC voltage is less than the under -voltage threshold the MCA1101 is in an inactive state. Vout and Vref both drive to ground. If the VCC voltage exceeds the under - voltage threshold Vout and Vref are released and will drive to approximately half the VCC supply voltage and an initial calibration will commence. Once the initial calibration has completed the MCA1101 becomes active. Vout will slew to indicate the value of current flowi ng in the IP+/ - conductor. Current flow in the IP+/- conductor with a VCC voltage less than the under -voltage threshold will not cause damage to the sensor. OVERCURRENT DETECTION (OCD) The MCA1101 have fast and accurate overcurrent fault detection circuitry. The overcurrent fault threshold ( I ) is user-configurable via an external resistor divider and supports a range of 120% to 200% of the full-scale primary input (IP). The overcurrent fault threshold ( I ) is set via a resistor divider from VCC to ground on the VOC pin. The voltage on the VOC pin (VVOC), may range from 0 × VCC to 0.5 × VCC. For +/-5A parts For V VOC between 0 × VCC and 0.2 25× VCC, the I threshold level is 1.2×IP. For V VOC between 0.225 × VCC and 0.35× VCC, the I threshold level is 1.5×IP. For VVOC between 0. 35× VCC and 0.5× VCC, the I threshold level is 2×IP. For +/-20A parts For V VOC between 0 × VCC and 0.2 25× VCC, the I threshold level is 1.2×IP. For V VOC between 0.225 × VCC and 0. 5× VCC, the I threshold level is 1.5×IP. For +/-50A parts For VVOC between 0× VCC and 0.5× VCC, the I threshold level is 1.2×IP. For +/-65A parts For VVOC between 0× VCC and 0.5× VCC, the I threshold level is 1.2×IP. If the input current exceeds the OC D threshold value I , the output pin will transition low and stay low, even if input current drops below the threshold. In order to reset the output, the user needs to bring VOC pin to VCC and hold it there for at least THvoc. Once the OCD function is reset, the VOC voltage should return back to its normal operating voltage Vvoc. A switch SW1 on Figure 1 can be used for this. Other methods are available as well. If OCD function is used, an OCD reset must be applied to the VOC pin after system power up, to put the OCD function and pin in a known state. The output is active low open drain. A pull-up resistor should be connected between and VCC. The VCC voltage will determine the high level of signal. low output voltage is below 200mV.The value of pull - up resistor is 2-10kOhm.
