Functional Description :

The Winson WCSA760 is a current switch designed for current switching

and current measuring. The current switching can be adjusted through

providing reference voltage to the Vset Pin. The output voltage (Vout) turns to

high voltage level when the internal voltage (VIP) is greater than the reference

voltage (Vset). In contrast, the output turns to the low level. Typical applications

include short circuit detection, over-current fault detection, and etc. For the

current measuring, it provides a precise solution for both DC and AC current

sensing in industrial, and users can also adjust the reference voltage value of

current switch mode on-site by measuring current mode.

The WCSA760 consists of a precise, low-temperature drift linear hall

sensor IC with temperature compensation circuit and a diameter 9.0 mm

through hole. Any current flowing through this hole will generate a magnetic

field which is sensed by the integrated Hall IC and converted into a

proportional output voltage.

The terminals of the conductive path are electrically isolated from the

sensor leads. This allows the WCSA760 current sensor to be used in

applications requiring electrical isolation without the usage of opto-isolators or

other costly isolation techniques.
