The CT430 (VCC = 5.0 V) 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 eight (8) 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.
Fast response with a 1 MHz bandwidth and 300ns response time. High signal-to-noise (SNR) with ultra-low noise of 9.0 mARMS. Integrated common mode field rejection of -54 dB to ensure stray fields do not impact measurements in the working application. The CT430 has an integrated over-current detection (OCD) circuitry to identify out of range currents which is output on the fault pin (FLT#). The FLT# is an open drain, active LOW digital signal.
The CT430 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 CT431.
