AS1826
Dual Outputs for both S and N-pole Low Power Hall-Effect Sensor IC
General Description
The total power consumption of AS1826 is typically less than 1.7uA at 1.8V power supply. AS1826 is designed to respond to alternating North and South poles. White 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).
