General Description
Using low power CMOS process, the AS1190OD 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 AS1190OD is typically less than 2.0uA at 2.8V power supply. AS1190OD 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.
