ALLEGRO CT8132BL-IS3

The CT813x series of omnipolar tunnel magnetoresistance (TMR) digital switches are designed for consumer and industrial applications. The devices are based on Allegro patented XtremeSenseTM 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.

For applications that require a very small form factor and low profile, the CT813x is assembled in a 4- lead LGA package. They are also available in an industry- standard 3- lead SOT- 23 package to support high- volume manufacturing for industrial markets.
