General Description
Using low power CMOS process, the AS1151OD
is designed for low power, high performance omnipolar
detection 3D hall-effect application. The 3D hall IC
integrated an on-chip hall voltage generator for
magnetic sensing, a comparator that amplifiers the hall
voltage, a Chopper amplifier, a Schmitt trigger to
provide switching hysteresis for noise rejection, and a
complementary output. The total power consumption of AS1151OD is
typically less than 1.3uA at 1.8V power supply. AS1151OD is designed to respond to alternating North
and South poles. When the magnetic flux density (B) is
larger than operate point (BOP), the output will be
turned on (low), the output is held until the magnetic
flux density (B) is lower than release point (BRP), then
turn off (high). The device is available in SOT23-3L and SIP-3L
Package and is rated over the -40°C to 125°C. The all
packages are RoHS and Green compliant
