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.



3.3V Single Supply

Immune to External Magnetic Fields by

Differential Sensing

200V_RMSWorking 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)



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.



Available in an SOIC-8 Package

APPLICATIONS

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.



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.

TYPICAL APPLICATION

MCS1800

3.3V

VCC

IP+

C_BYP

0.1µF

V_OUT

VOUT

I_P

IP-

FILT

GND

C_F

Note:

1) V_OUTis proportional to I_Pwithin the specified range. The noise vs. bandwidth tradeoff can be adjusted by connecting a capacitor (C_F) between

FILT and GND.
