Description
The AH1891 is a miniature 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 has been 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 7uA. 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.
The outputs of the AH1891 are switched with either a North or
South pole of sufficient strength. When the magnetic flux
density (B) is larger than operate point (Bop), Output 1 will
pull low and Output 2 will be inverted (high). The output states
are held until B is lower than release point (Brp).
The AH1891 is available in U-WLB0808-4 package.
