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.

Notes:

5)
See the Operation section on page 12 for more details.
Beyond the maximum specified current range (IP), the current sensor continues to provide an analog output voltage proportional to the
primary current until the device reaches the high or low saturation voltage. 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 output is filtered.
9)
Guaranteed by design.
10) Guaranteed by characterization.
11) Typical values denoted with the “±” sign signify ±3 sigma values.
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.

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.

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.

treatment (the resolution is typically 3 times the
RMS noise).

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

The total output error incorporates all error
sources, and is a function of IP. 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.

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).

The rising time (tR) is defined as the time
between the following moments:
1. t1: The sensor’s VOUT reaches 10% of its full
scale value.
2. t2: The sensor’s VOUT reaches 90% of its full
scale value (see Error! Reference source

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.
