Isolated, 500kHz TMR Current Sensor in 1 mΩ SOIC-8 Package
Detailed Description
The CT4022, offered in an SOIC-8 package, and the CT4032, offered in an SOICW-16 package, are 500 kHz, ultra-low noise TMR current sensors.
The CT4022 can achieve up to 15 times lower integrated noise levels compared to traditional Hall-effect sensors.
These TMR sensors are differential which enables common-mode field rejection to cancel out stray magnetic fields. The primary conductor resistance of both packages is 1 mΩ, which enables the sensor to withstand high inrush 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.
