Allegro MicroSystems CT220 Evaluation Tools include the EVB222 and CTD22x demo boards. The EVB222 is a break-out evaluation board that is designed to demonstrate the current sensing capabilities of the CT220 linear magnetic sensor. The CTD22x is a contactless current sensor demo board designed to perform contactless current measurements from PCB traces and busbars of varying widths and separations from CT220. Allegro MicroSystems CT220 Evaluation Tools demonstrate the capability of the CT220 TMR field sensors.
