Overview
AX8101/A MicroPower, Ultra-sensitive Hall Effect Switch  GENERAL DESCRIPTION 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.
While the magnetic flux density (B) is larger than operate point (Bop), the output will be turned on; the output is latched until B is lower than release point (Brp).
