MCS1800 3.3V, Linear Hall-Effect Current Sensor with ±3% Accuracy Over Temperature DESCRIPTION FEATURES The MCS1800 is a linear Hall-effect current sensor for AC or DC current sensing. The Hall array is differential, which cancels out any stray magnetic field.              A primary conductor with a low resistance allows current to flow close to the IC, which contains high-accuracy Hall-effect sensors. This current generates a magnetic field that is sensed at two different points by the integrated Hall-effect transducers. The magnetic field difference between these two points is then converted into a voltage that is proportional to the applied current. A spinning current technique is used for a low stable offset. The galvanic isolation between the pins of the primary conductive path and the sensor leads allows the MCS1800 to replace opto-isolators or other isolation devices.  The MCS1800 requires a minimal number of readily available, standard external components. The device’s small footprint saves board area and makes it well-suited for space-constrained applications. The MCS1800 is available in an SOIC-8 package.      3.3V Single Supply Immune to External Magnetic Fields by Differential Sensing 200VRMS Working Voltage for Basic Isolation Operating Temperature: -40°C to +125°C 1.2mΩ Internal Conductor Resistance ±12.5A and ±25A Range Adjustable Bandwidth Up to 100 kHz 4μs Output Rising Time Ratiometric Output from Supply Voltage Output Proportional to AC or DC Currents Factory-Trimmed for Accuracy No Magnetic Hysteresis Integrated Shield Suppressing Capacitive Coupling from Current Conductor to Die (Up to 10V/ns) Available in an SOIC-8 Package APPLICATIONS Motor Control Automotive Systems Load Detection and Management Switch-Mode Power Supplies Over-Current Fault Protection All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.

However, the nonlinearity increases beyond the specified range (IP). 6) The device can operate at higher primary current levels (IP) and ambient temperatures (TA), as long as the device does not exceed the maximum junction temperature (TJ (MAX)). 7) The offset voltage does not incorporate any error due to external magnetic fields. 8) Percentage of IP, when IP = IP_MAX.

The resistance is defined as the total resistance measured from a point of the lead next to the solder joint, assuming that the two IP+ pins (and IP- pins) have the same potential (see Figure 1). This definition corresponds to the effective resistance used to estimate the Joule heating, calculated with R x IP2.

All Rights Reserved. 11 MCS1800 – 3.3V, LINEAR HALL-EFFECT CURRENT SENSOR WITH ±3% ACCURACY OPERATION Current Rating IPMAX is the rated current. The sensor output is linear, as a function of the primary current (IP). IPMAX follows the specified performances when IP is between -IPMAX and + IPMAX (see Figure 3). Other deviations are systematic, which means that they represent the average deviation across a large number of data points. These deviations can be removed by calibrating the device. VOUT VCC VCC / 2 0 -IPMAX IP 0 +IPMAX Figure 3 : Sensor Output Function Sensitivity (SENS) The sensitivity (SENS) (in mV/A) indicates how the output changes when the primary current changes. SENS the product of the average between the two coupling constants (PMCF1 and PMCF2) (in mT/A) and the transducer gain (in mV/mT). The gain is factory-trimmed to the sensor target sensitivity. Coupling constants (PMCF1 and PMCF2) Figure 4 shows a cross-section of the sensor. The first and second Hall magnetic coupling factors are defined as the amount of the vertical magnetic field (B1 and B2) produced at the sensing points 1 and 2, per unit of current injected in the primary conductor. Due to the asymmetrical shape of the primary conductor, the magnetic field generated in the two sensing points are different. B1 Sensing Point 1 Primary Conductor divided by the sensitivity (in mV/A). VNOISE represents the smallest current that the device is able to resolve without any external signal treatment (the resolution is typically 3 times the RMS noise). Sensing Point 2 B2 Figure 4: Cross Section of the Sensor Noise (VNOISE) The noise (VNOISE) is a random deviation that cannot be removed by calibrating the device. The input’s referred noise is the root mean square of the sensor’s output noise (in mV) Zero Current Output Voltage (VOUT(Q)) VOUT(Q) is the voltage output when the primary current is 0A. The nominal value is VCC / 2. The variation in VOUT(Q) from the nominal value is due to thermal drift, as well as the factory’s resolution limits related to voltage offset trimming. Offset Voltage (VOE) The offset voltage (VOE) is the difference between VCC / 2 and the zero current output voltage. To convert this voltage into amperes, divide VOE by the sensitivity. Nonlinearity (ELIN) The primary current and sensor output should have a linear relationship, indicated by a straight line. A line that is not straight indicates nonlinearity, which is a deviation. Nonlinearity (in %) can be calculated with Equation (1): ELIN  Max(VOUT (IP )  VLIN (IP ))  100 (1) VOUT (IPMAX )  VOUT ( IPMAX ) Where VLIN(IP) is the approximate straight line calculated by the least square method. Note that depending on the curvature of VOUT(IP), ELIN can be positive or negative. Total Output Error (ETOT) ETOT (in %) is the relative difference between the sensor output and the ideal output at a given primary current (IP). ETOT can be estimated with Equation (2): ETOT (IP )  VOUT (IP )  VOUT_IDEAL (IP ) SENS  IP MCS1800 Rev. 1.0 MonolithicPower.com 4/13/2021 MPS Proprietary Information. Patent Protected.

At currents close to IPMAX, ETOT is affected mainly by the sensitivity error. At currents close to 0A, ETOT is mostly caused by the offset voltage (VOE). Note that when IP = 0A, ETOT diverges to infinity due to the constant offset. VCC VCCTYP 90% of VOUTNOR VOUT VCCMIN tPO 0 t1 t2 t Figure 5: Power On Time (tPO) Ratiometry Coefficients Generally, the sensor output is ratiometric. This means that the sensitivity and the zero current output scale with VDD. The ratiometry coefficients measure if the sensitivity and zero output current are proportional. Propagation Delay (tPD) The propagation delay (tPD) represents the internal latency between an event that has been measured and the sensor’s response. tPD is defined as the time between the following moments: KSENS can be estimated with Equation (4): 1. t1: The primary current signal reaches 20% of IP_MAX. K SENS  SENS(VCC) / SENS(3.3V) VCC / 3.3V (4) KVO can be calculated with Equation (5): K VO  VOUT (IP  0V to VCC) / VOUT (IP  0V to 3.3V) VCC / 3.3V (5) It is recommended for KSENS and KVO to be equal to 1. Power On Time (tPO) The power on time (tPO) is the time interval after power is first applied to the device, until the output can correctly indicate the applied primary current. tPO is defined as the time between the following moments:   t1: The supply reaches the minimum operating voltage (VCCMIN). t2: VOUT settles within ±10% of its steady state value under an applied primary current (see Figure 5). 2. t2: VOUT reaches 20% of VOUTMAX (see Figure 6).

All Rights Reserved. 14 MCS1800 – 3.3V, LINEAR HALL-EFFECT CURRENT SENSOR WITH ±3% ACCURACY APPLICATION INFORMATION Self-Heating Performance The conductor and MCS1800 temperatures can rise when current flows through the primary conductor. This means that self-heating should be carefully verified to ensure that the IC junction temperature does not exceed the maximum value (see the Absolute Maximum Ratings on page 5). Figure 11 shows the top and bottom layers of the PCB. The board includes a total of 2200mm2, 4oz (139µm) copper connected to the primary conductor by the IP+ and IP- pins. The copper covers both the top and bottom sides, and thermal vias connect the two layers. The thermal behavior strongly depends on the thermal environment of the IC, as well as its cooling capacity. In particular, thermal behavior depends on the PCB copper area’s thickness. The thermal response is also related to the current waveform’s profile (e.g. the amplitude and frequency of an AC current, or the peaks and duty cycle of a pulsed DC current). Figure 10 shows the self-heating performance of the MCS1800 with a DC current input. The data is collected when the MCS1800 is mounted on the device’s evaluation board and TA = 25°C. Values were taken 10 minutes after a continuous current.
