KUALA LUMPUR, Oct 26 -- Crocus Technology Inc, the leading supplier of disruptive Tunnel Magneto-Resistance XtremeSense® sensors, has announced the CT425, CT426, CT427 and CT428 isolated current sensors with less than one per cent total error over the full operating temperature range without sacrificing accuracy or bandwidth.
According to a statement, the high-speed operation and accurate output allow customers to optimise system design for smaller size and higher efficiency.
“The expansion of this product family brings more options to our customers to experience the high precision performance of our XtremeSense TMR products in more demanding applications,” said President and Chief Executive Officer of Crocus Technology, Zack Deiri.
The CT42x with less than 300 ns response time greatly simplifies the solution in EV Charging applications which are utilising GaN (Gallium Nitride) or SiC (Silicon Carbide) transistors to improve power density.
Likewise, the CT42x offers improvements in terms of performance and size compared to the classic isolated current sense solutions which utilise a shunt resistor, amplifier, and digital isolator to sense the voltage and convert this signal into a current measurement.
The CT42x directly senses the flow of current through the package avoiding errors in conversion and provides inherently faster and more accurate measurements.
With industry leading response time of 300 ns, high power architectures like the CCM Totem-Pole PFC can provide higher power density solutions.
Crocus’ proprietary TMR technology inherently offers a very high signal-to-noise ratio (SNR) which allows for high resolution measurements required for precision control or monitoring applications.
