August 2020 CT220 XtremeSense High Linearity, High-Resolution TMR Contactless Current Sensor in Miniature Form Factor Features Product Description The CT220 is a high linearity and high-resolution AC or DC Contactless Current Sensing Range: Up to contactless current sensor from Crocus Technology 1,000 A developed on its patented XtremeSense TMR technology o Resolution: 5 mA with the capability of measuring up to 1,000 A. It measures Inherently High Isolation the magnetic field of the current flowing through a busbar Magnetic Field (Current) Range: or printed circuit board (PCB) trace and converts it to an o 1.5 mT analog output voltage that represents the field and o 5.0 mT therefore current. o 10.0 mT o 15.0 mT As a contactless current sensor, it has an inherently high Stable Performance over Temperature isolation making it an ideal solution for applications where Supply Current: ~1.2 mA product safety compliance is a requirement due to high FLAG Pin to Indicate 90% and 10% of Full Field operating voltages combined with human interaction with Range the product. The CT220 achieves XtremeSense o Active LOW Digital Output (Push-pull) performance with a typical total out error of 0.5% while Supply Voltage: 2.7 V to 5.5 V sensing field (current) as low as 5 mA. It supports a wide Operating Temperature Ranges: operating voltage range of 2.7 V to 5.5 V. o Industrial: -40C to +85C o Extended Industrial: -40C to +125C The CT220 is an ideal contactless current sensing solution Package: 5-lead SOT23 for applications that need to have excellent isolation and accurate current measurements. There are four (4) variants Applications of the CT220 that will sense the following magnetic fields: 1.5 mT, 5.0 mT, 10.0 mT and 15.0 mT. It also Contactless Current Sensing Measurements integrates a FLAG output that is active LOW and will Motor Control indicate when the field is above 90% and below 10% the Solar Inverters full field range. Power Distribution Units (PDUs) UPS, SMPS and Telecom Power Supplies It is available in an industry standard 5-lead SOT23 Smart Appliances package.
