Functional Description :

The Winson WCS2810 provides economical and precise solution for both DC and

AC current sensing in industrial, commercial and communications systems. The

unique package allows for easy implementation by the customer. Typical applications

include motor control, load detection and management, over-current fault detection

and any intelligent power management system etc…

The WCS2810 consists of a precise, low-temperature drift linear hall sensor IC

with temperature compensation circuit and a current path with 0.4 mΩ typical

internal conductor resistance. This extremely low resistance can effectively reduce

power loss, operating temperature and increase the reliability greatly. Applied

current flowing through this conduction path generates a magnetic field which is

sensed by the integrated Hall IC and converted into a proportional voltage.

The terminals of the conductive path are electrically isolated from the sensor

leads. This allow the WCS2810 current sensor to be used in applications requiring

electrical isolation without the use of opto-isolators or other costly isolation

techniques and make system more competitive in cost.
