The CT81xx is a product family of Tunnel Magneto-resistance (TMR) digital latches and analog sensors that are designed for consumer and industrial applications. They are based on Crocus Technology’s patented XtremeSense® TMR technology with integrated CMOS process to provide a monolithic solution for superior sensing performance. The CT81xx series of magnetic sensors offer stable magnetic operation over the operating temperature range. With very high sensitivity, the CT81xx products enable larger air gaps or smaller size/lower cost magnets to be used in systems while also drawing supply current as low as 110 nA. As such, these magnetic sensors are ideal for battery operated products where minimal current consumption is required. The outputs for both the digital latches and analog sensors are ratio-metric which provide greater design flexibility when interfacing with a variety of micro controllers.
Available in an industry standard 3-lead SOT23, 5-lead SOT23 and small form factor 4-lead LGA packages to support both consumer and industrial applications.
