CQ209A Overview

As a safety precaution, current sensors are placed in Module packages. Tray protects the current sensors from damage. There should be 9mA maximum current supplied by these current sensors. If the current supplied by the current sensor is greater than 9mA, then the sensor should be faulty. It is essential that these current sensors work at a temperature above -40°C. It is important to set the maximum operating temperature of the current sensors to 90°C.
