Description

WCS2202 Hall effect current sensor provides economical and precise solution for both AC as well as DC 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.

WCS2202 Current Sensor has a built in AC to DC rectifier circuit so you can directly connect this sensor to your ADC or your microcontroller to measure AC current. No need of any signal conditioning circuit.

WCS2202 Current Sensor 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 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 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.
