OBSOLETE –NPEAWRPTRDOIDSCUCOTNTINUED PART OBSOLETE - USE AH1898 / AH1892 AH1891 MINIATURE MICROPOWER OMNIPOLAR HALL EFFECT SWITCH Description The AH1891 is a minature micropower Omnipolar Hall effect switch IC with dual outputs, specifically designed for portable and battery powered equipment such as cellular phones and portable PCs.
To support battery powered equipment the AH1891 is optimized to operate over the supply range of 1.
8V to 3.
3V and uses a sleep function to give an average supply current of only 7µA.
To minimize PCB space the AH1891 is packaged in the small CSP package (0.
8mmx0.
8mm) and the design integrates the external pull up resistors to simplify the applications circuit...
