Functional Description

The Winson WCS37A50 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 intellige

nt power management system etc…

The WCS37A50 consists of a precise, low-temperature drift linear hall sensor

IC with temperature compensation circuit and a current path with 1.5

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

voltage.

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

leads. This allow the WCS37A50 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.
