Battery Management Systems Product Description
The CT220 is a high linearity and high-resolution
contactless current sensor from Crocus Technology
developed on its patented XtremeSense TMR technology
with the capability of measuring up to 1,000 A. It measures
the magnetic field of the current flowing through a busbar
or printed circuit board (PCB) trace and converts it to an
analog output voltage that represents the field and
therefore current.
As a contactless current sensor, it has an inherently high
isolation making it an ideal solution for applications where
product safety compliance is a requirement due to high
operating voltages combined with human interaction with
the product.
The CT220 achieves XtremeSense™
performance with a typical total out error of ±0.5% while
sensing field (current) as low as 5 mA. It supports a wide
operating voltage range of 2.7 V to 5.5 V.
The CT220 is an ideal contactless current sensing solution
for applications that need to have excellent isolation and
accurate current measurements. There are four (4) variants
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
integrates a FLAG output that is active LOW and will
indicate when the field is above 90% and below 10% the
full field range.
It is available in an industry standard 5-lead SOT23
package. Battery Chargers
