MCS1801

5V, Linear Hall-Effect Current Sensor

with ±3% Accuracy Over Temperature

DESCRIPTION

FEATURES

The MCS1801 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.

•

5V Single Supply

Immune to External Magnetic Fields by

Differential Sensing

200V_RMSWorking Voltage for Basic Isolation

-40°C to +125°C Operating Temperature

1.2mΩ Internal Conductor Resistance

±12.5A and ±25A Range

Adjustable Bandwidth Up to 100kHz

4μs Output Rising Time

Ratiometric Output from Supply Voltage

Output Proportional to AC or DC Currents

Factory-Trimmed for Accuracy

No Magnetic Hysteresis

•

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 and stable offset.

Available in an SOIC-8 Package

The galvanic isolation between the pins of the

primary conductive path and the sensor leads

allows the MCS1801 to replace opto-isolators or

other isolation devices.

The MCS1801 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 MCS1801 is available in an

SOIC-8 package.

VCC

IP+

V_OUT

C_BYP

VOUT

I_P

IP-

FILT

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.
