DESCRIPTION
APE9105 is a three-terminal Hall Effect sensor device
with an output driver, mainly designed for battery–operation,
hand-held equipment (such as Cellular and Cordless Phone,
PDA). For APE9105, either north or South Pole of sufficient
strength will turn the output on. 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 (low), the output is latched until B is lower than release
point (Brp), then turned off.
