ments The AH9251 is a medium sensitivity Hall-effect switch with internal pull-up resistor on the output, designed for battery operated handheld equipments to industrial applications. A chopper stabilized architecture improves stability of magnetic switch points over the whole operating range. A sleep-awake logic controls the sleep and awake time to reduce the average operating current of the device. During the awake time, the output is changed with the magnetic flux density. During the sleep time, the output is latched in its previous state and the current consumption reduces to 4µA typical at 3V. The average current cons
