DESCRIPTION
The CT813x series of omnipolar tunnel magnetoresistance (TMR) digital switches 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 CT813x digital switches offer stable magnetic operation over the operating temperature range.
This product family has very low power consumption- as low as 110 nA- which is ideal for battery-operated products where minimal current consumption is required. The devices support magnetic fields down to 9 G for applications where there is a large air gap requirement....
