The CT430 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 six (6) current ranges where the integrated current carrying conductor (CCC) will handle up to 50 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.
It has less than 1.0 µs output response time while the current consumption is about 6.0 mA and is immune to common mode fields. The CT430 has an integrated over-current detection (OCD) circuitry to identify out of range currents (OCD) with the result outputted to the fault-bar (FLT) pin. The FLT is an open drain, active LOW digital signal that is activated by the CT430 to alert the microcontroller that a fault condition has occurred.
The CT430 is offered in an industry standard 16-lead SOIC-Wide package that is “green” and RoHS compliant
