CT450: 1 MHz Bandwidth Contactless Current Sensor with <1% Total Error Product Image

These parts are in production but have been determined to be NOT FOR NEW DESIGN.

This classification indicates that sale of this device is currently restricted to existing customer applications. The device should not be purchased for new design applications because obsolescence in the near future is probable. Samples are no longer available.

We recommend the CT455 or CT456 as a replacement part.

Description

Top Features

Typical Applications

Packaging

The CT450 is a high bandwidth and low noise integrated contactless current sensor that uses Allegro MicroSystems’ patented XtremeSense™ TMR technology to enable high accuracy current measurements for many consumer, enterprise, and industrial applications. It supports fixed and programmable field ranges where the CT450 sense and translate the magnetic field into a linear analog output voltage. It achieves a total error output better 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.
