Allegro MicroSystems CTD453 Current Sensor Development Tools

Allegro MicroSystems CTD453 Current Sensor Development Tools showcase the advantages of contactless current sensing using the CT453 XtremeSense® TMR Contactless Current Sensors. CTD453 boards feature a full-bridge configuration comprised of four TMR elements with active CMOS circuitry that enables high bandwidth and high-accuracy current measurements. The four-layer PCB performs contact current sensing for two ranges: using PCB traces for <75APK current and using a busbar for 300ANOMINAL current.
