Allegro MicroSystems’ CT455

It supports two standard field ranges where the CT455 senses and translates the magnetic field into a linear analog output voltage.

CT455 is also available in a user-programmable variant, which enables end-of-line calibration of gain and offset. While the sensor is pre-programmed to compensate for gain and offset temperature drift, the ability to adjust offset and gain relaxes mechanical tolerances during sensor mounting.

It has less than 300ns output response time while the current consumption is about 6.0 mA. The CT455 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.

Unlike other market solutions, Allegro's CT455 TMR sensor offers distinct advantages, as it is designed to enable smaller, more efficient, high-accuracy current measurements on PCB or Busbar applications from 80 up to above 800A, depending on the configuration, with the best performance advantages in the 80-200A range.

Additionally, unlike traditional high-power current sensors, the CT455 offers a contactless, non-intrusive solution that delivers 1MHz bandwidth and a 300ns response time to enable faster power conversion. For those seeking to maximise power while minimising their footprint, the compact design, enhanced reliability and efficiency improvements of Allegro’s latest sensors make them an ideal choice.
