Datasheet Summary
AX8112 MicroPower, Ultra-sensitive Hall Effect Switch
GENERAL DESCRIPTION AX8112 is a Hall Effect sensor device with Dual output driver, mainly designed for battery- operation, hand-held equipment (such as Cellular and Cordless Phone, PDA). For AX8112, the total operation power is down to 10uW in the 1.8V supply. Either north or South Pole of sufficient strength will turn the output on. The output will be turned off under no magnetic field. When the magnetic flux density (B) is larger than operate point (Bop) the output is switched on. The output is turned off when B bees lower than the release point (Brp). The output will remain off when there is no magnetic field. The AX8112 has two...
