CT431-ESWF20MR Crocus

April 2022 CT431 XtremeSense TMR Ultra-Low Noise, <1% Total Error Current Sensor Features Product Description Integrated Contact Current Sensing for Low to The CT431 is a high bandwidth and ultra-low noise integrated contact current sensor that uses Crocus Medium Current Ranges: o 0 A to +20 A Technologys patented XtremeSense TMR technology to enable high accuracy current measurements for many o -20 A to +20 A o 0 A to +30 A consumer, enterprise, and industrial applications. It supports nine (9) current ranges where the integrated o -30 A to +30 A o -40 A to +40 A current carrying conductor (CCC) will handle up to 65 A of current and generates a current measurement as a linear o 0 A to +50 A o -50 A to +50 A analog output voltage. It achieves a total output error of less o 0 A to +65 A than 1.0% full-scale (FS) over voltage and the full o -65 A to +65 A temperature range. Integrated Current Carrying Conductor (CCC) It has about a 300 ns output response time while the current Linear Analog Output Voltage consumption is about 6.0 mA and is immune to common Total Error Output 1.0% FS, -40C to +125C mode fields. The CT431 has an integrated over-current 1 MHz Bandwidth detection (OCD) circuitry to identify out of range currents Response Time: ~300 ns (OCD) with the result outputted to the fault-bar (FLT) pin. UL/IEC 62387 Certification The FLT is an open drain, active LOW digital signal that is o Rated Isolation Voltage: >5 kVRMS activated by the CT431 to alert, for example a o Working Voltage for Basic Isolation: >1287 V RMS microcontroller that a fault condition has occurred. o Working Voltage for Reinforced Isolation: >647 V RMS The CT431 is offered in an industry standard 16-lead SOIC- IEC 61000-4-5 Certification Wide package that is green and RoHS compliant. Low Noise: 9.5 mARMS to 19.0 mARMS fBW = 100 kHz Reference Voltage Output for AC/DC Current Measurements VOUT VREF < 1.0% FS, -40C to +125C Immunity to Common Mode Fields: -54 dB Supply Voltage: 3.0 V to 3.6 V Over-Current Detection (OCD) o Out of Range Currents AEC-Q100 Grade 1 (Under Qualification) 16-Lead SOIC-Wide Package Applications Solar/Power Inverters UPS, SMPS and Telecom Power Supplies Battery Management Systems Motor Control White Goods Power Utility Meters Over-Current Fault Protection 2022 Crocus Technology 1 CT431 Rev. 1.0 CT431 www.crocus-technology.com Part Ordering Information Auto Operating Current Packing Part Number Package Grade Temperature Range Range Method CT431-ESWF20DR - -40C to +85C CT431-HSWF20DR - 0 A to +20 A -40C to +125C CT431-ASWF20DR Grade 1 CT431-ESWF20MR - -40C to +85C CT431-HSWF20MR - -20 A to +20 A -40C to +125C CT431-ASWF20MR Grade 1 CT431-ESWF30DR - -40C to +85C CT431-HSWF30DR - 0 A to +30 A -40C to +125C CT431-ASWF30DR Grade 1 CT431-ESWF30MR - -40C to +85C CT431-HSWF30MR - -30 A to +30 A -40C to +125C CT431-ASWF30MR Grade 1 16-lead SOIC-Wide CT431-HSWF40MR - -40C to +125C -40 A to +40 A Tape & Reel 10.21 x 10.31 x 2.54 mm CT431-ESWF50DR - -40C to +85C CT431-HSWF50DR - 0 A to +50 A -40C to +125C CT431-ASWF50DR Grade 1 CT431-ESWF50MR - -40C to +85C CT431-HSWF50MR - -50 A to +50 A -40C to +125C CT431-ASWF50MR Grade 1 CT431-ESWF65DR - -40C to +85C CT431-HSWF65DR - 0 A to +65 A -40C to +125C CT431-ASWF65DR Grade 1 CT431-ESWF65MR - -40C to +85C CT431-HSWF65MR - -65 A to +65 A -40C to +125C CT431-ASWF65MR Grade 1 Evaluation Board Ordering Information Operating Temperature Part Number Current Range Range CTD431-20DC 0 A to +20 A CTD431-20AC -20 A to +20 A CTD431-30DC 0 A to +30 A CTD431-30AC -30 A to +30 A -40C to +125C CTD431-50DC 0 A to +50 A CTD431-50AC -50 A to +50 A CTD431-65DC 0 A to +65 A CTD431-65AC -65 A to +65 A 2022 Crocus Technology 2 CT431 Rev. 1.0
