NEW PRODUCT AH1898 PROGRAMMABLE MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description The AH1898 is a micropower magnetic range selectable (Bop/Brp) Omnipolar Hall effect switch IC with internal pull up and pull down capability, designed for portable and battery powered consumer equipment such as cellular phones and portable PCs. To support battery powered equipment and low voltage microcontrollers, the AH1898 can operate over the supply range of 1.6V to 3.6V and uses a hibernating clocking system to minimize the power consumption. The average supply current is only 4.3µA typical at 1.80V. The AH1898 has an 8kV ESD rating on the supply and output pins. To minimize PCB space, the AH1898 is packaged in the small CSP package (0.81mm x 0.81mm typical).
