The CT812x series of bipolar tunnel magnetoresistance (TMR) digital latches are designed for consumer and industrial applications. The devices are based on Allegro patented XtremeSense™ TMR technology with integrated CMOS process to provide a monolithic solution for superior sensing performance. The CT812x digital latches offer stable magnetic operation over the operating temperature range.
This product family has very low power consumption—as low as 2.2 µA—which is ideal for battery-operated products where minimal current consumption is required. The devices support magnetic fields down to 10 G for applications where there is a large air gap requirement.
The CT812x is available in an industry-standard 3-lead SOT-23 package to support high-volume manufacturing for industrial markets
