The CT403x is a highly linear, XtremeSense® TMR based Current Sensor. The TMR sensor is differential which enables common-mode field rejection to cancel out stray magnetic fields. The primary conductor is only 0.5 mOhm which enables the sensor to withstand high in-rush current and minimize power loss. The current applied to the pin of the primary conductor generates an internal differential magnetic field. The TMR sensor provides a proportional voltage to the differential magnetic field while rejecting common-mode stray magnetic fields.
The pins of the primary conductive path and the sensor leads are galvanically isolated. This enables high-side current sensing without the need for additional isolation techniques.
The CT403x family is offered in an industry standard 16-lead SOICW package that is “green” and RoHS compliant.
