CT428 XtremeSense® TMR Current Sensor with Ultra-Low Noise and <0.7% Total Error
2022-11-11
●PRODUCT DESCRIPTION
■The CT428 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).
■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 CT428 has an integrated over-current detection (OCD) circuitry to identify out of range currents (OCD) with the result outputted to the fault-bar (F̅ L̅ T̅ ) pin. The F̅ L̅ T̅ is an open drain, active LOW digital signal that is activated by the CT428 to alert the microcontroller that a fault condition has occurred.
■The CT428 is offered in an industry standard 8-lead SOIC package that is “green” and RoHS compliant.
