Functional Description :

The Winson WCS2202 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 WCS2202 consists of a precise, low-temperature drift linear hall

sensor IC with temperature compensation and AC to DC rectifier circuit and a

current path with 8.3 m

Ω 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 rectified DC voltage.

The terminals of the conductive path are electrically 1,000V isolated from

the sensor leads. This allow the WCS2202 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.
