Functional Description :

Winson’s WCS1301,1302,1303 and 1304 provides cheap and convenient

solution for current detection in industrial and commercial electronic systems.

Typical applications include short circuit detection, load detection and

over-current fault detection etc…

The WCS1301~4 consists of a precise, low-temperature drift hall switch IC

with temperature compensation circuit and a current path with typical 8.3 m

Ω

internal conductor resistance. This extremely low resistance can effectively

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

Measured current IP flowing through this conduction path generates a

magnetic field which is sensed by the integrated Hall switch IC and output

“Low” when IP>=Iop and output “High” when IP<Irp.

The terminals of the conductive path are electrically isolated from the

sensor leads. This allow the WCS1301~4 current switch 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.
