The CT432 is a high bandwidth and ultra-low noise integrated contact 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 multiple current ranges where the integrated current carrying conductor (CCC) will handle up to 65 A of current and generates a current measurement as a linear analog output voltage. It achieves a total output error of less than ±1.0% full-scale (FS) over supply voltage and the full temperature range.

It has about a 300 ns output response time while the current consumption is about 6.0 mA and is immune to common mode fields. The CT432 was optimized for high dV/dt applications which minimizes capacitive coupling to VOUT allowing CT432 to be used in switching applications.

The CT432 is offered in an industry-standard 16-lead SOIC- Wide package that is “green” and RoHS compliant.

Also available in 3.3 V version as CT433.
