APE9101/A-HF-3

DESCRIPTION

The APE9101/A-HF-3 is a three-terminal Hall Effect

sensor device with an output driver, mainly designed

for battery operated hand-held equipment (such as

cellular and cordless phones, PDAs). After power-on,

the APE9101/A-HF-3 will detect and setup the operating

pole (North or South) to avoid another side magnetic

noise. (Patent pending). For the APE9101-HF-3, the

output will be turned off in the absence of a magnetic field.

While the magnetic flux density B is larger than the

operating point, Bop, the output will be turned on. The

output remains latched on until the flux density B drops

below the release point, Brp.
