AH180; Omnipolar hall effect sensor switch from Diodes Inc

AH180 is used to detect lid position sensing in flip phone or any such hand held smart gadgets. This omnipolar hall effect sensor operated at low voltage and ultra sensitive. Power consumption is reduced through a clocking scheme to minimize the "ON" duty cycle.
Since it's omnipolar, can operate by either north or south pole, eliminating the need for orienting the magnet’s polarity on your PCB. Has on-chip filters to derecognize false magnetic fields and also protect AH180 from DC and RF noise which is plenty in mobile communication devices.
