Crocus Technology CT42X Current Sensor

The CT42x family is a high bandwidth, fast response 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. The Crocus sensor supports six (6) 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 voltage and the full temperature range. 

To meet the requests from customers the new CT42x family is expanding with four available configurations that are pin-to-pin and footprint compatible to Allegro/Melexis products: CT427/CT428 have a FAULT pin, CT425/CT426 have a FILTER pin. CT425/CT428 = 5 V, CT426/CT427 = 3.3 V. The CT42x is offered in SOIC-8 package.
