Product Description
The CT450 is a high bandwidth and low noise integrated
contactless current sensor that uses Crocus Technology’s
patented XtremeSense TMR technology
to enable high
accuracy current measurements for many consumer,
enterprise, and industrial applications. It supports six (6)
field ranges where the CT450 senses and translates the
magnetic field into a linear analog output voltage. It
achieves a total error output of less than ±
1.0% over
voltage and temperature.
It has less than 300 ns output response time while the
current consumption is about 6.0 mA. The CT450 is
equipped with a filter function to reduce the noise on the
output pin.
The CT450 is housed in an 8-lead SOIC package and a
very low profile, industry standard 8-lead TSSOP package
that are both “green” and RoHS compliant.
Applications
• Solar/Power Inverters
• Battery Management Systems
• Smart Fuse Over-Current Detection
• Industrial Equipment
• Power Utility Meters
• Power Conditioner
• DC/DC Converters
