AX8101 Overview
AX8101/A is a three-terminal Hall Effect sensor device with a output driver, mainly designed for battery operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). After power-on, AX8101/A will detect and setup the operating pole (North or South) to avoid another side magnetic noise (Patent pending). For AX8101, the output will be turned off under no magnetic field.
