CT433 Datasheet Tmr Current Sensor

Manufacturer: Allegro MicroSystems

Overview: CT433 XtremeSense™ TMR Current Sensor with High dV/dt Immunity, 5 kV Isolation, and mon-Mode Field.

General Description

The CT433 is a high bandwidth and ultra-low noise integrated contact current sensor that uses Allegro patented XtremeSense™ TMR technology to enable high accuracy current measurements for many industrial, consumer and automotive applications.

The device supports multiple current ranges where the integrated current carrying conductor (CCC) will handle up to 70 A of current and generates a current measurement as a linear analog output voltage.

The device achieves a total output error of less than ±1.0% full-scale (FS) over voltage and the full temperature range.
