MCS1806

3kV_RMSIsolated Hall-Effect Current Sensor

with 500V_RMSWorking Voltage, ±2.5% Accuracy

DESCRIPTION

FEATURES

The MCS1806 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 or 5V Single-Supply Options

Immune to External Magnetic Fields via

Differential Sensing

3kV_RMSMinimum Isolation Voltage

500V_RMSMaximum Working Voltage

±2.5% Total Accuracy

0.9mΩ Internal Conductor Resistance

±5A to ±50A Bidirectional Range

Adjustable Bandwidth Up to 100kHz

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

the 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.

Available in an SOIC-8 Package

The galvanic isolation between the pins of the

primary conductive path and the sensor leads

allows the MCS1806 to replace optoisolators

and other isolation devices.

The MCS1806 requires a minimal number of

readily available, standard external components.

The device’s small SOIC-8 footprint saves board

area and makes it well-suited for space-

constrained applications.

APPLICATIONS

•

Multi-Phase Inverters

Motor Controls

Automotive Systems

Load Detection and Management

Switch-Mode Power Supplies

Over-Current Fault Protection
