SLYA065 October 2022 TMAG5328
By connecting the TMAG5328 to a DAC with nonvolatile memory, a software programmable Hall-effect switch with microcontroller-less standalone mode can be implemented. Using a DAC also enables backcalculating the magnetic flux density seen by the device. In addition, the DAC can be configured to implement diagnostics on the TMAG5328 to detect TMAG5328 pin shorts, TMAG5328 pin disconnections, and magnet out of range faults. These applications as well as the other applications of the TMAG5328 adjustable BOP increases system design flexibility and reduces design time.
