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 becomes
lower than the release point (Brp). The output will remain off when there is no magnetic
field. The AX8112 has two outputs, output one pulls low when switched on and output two
is inverted.
FEATURES
