AH3574

NEW PRODUCT Description The AH3574 is a high voltage high sensitivity Hall Effect Omnipolar switch IC designed for proximity, position and level sensing in consumer home appliances, office equipment, smart home to industrial applications. To support wide range of demanding applications, the design has been optimized to operate over the supply range of 3.0V to 28V. With chopper stabilized architecture and an internal bandgap regulator to provide temperature compensated supply for internal circuits, the AH3574 provides a reliable solution over the whole operating range. For robustness and protection, the device has a reverse blocking diode with a Zener clamp on the supply. The output has an over current limit and a Zener clamp. The single open drain output can be switched on with South or North pole of sufficient strength. When the magnetic flux density (B) perpendicular to the package is larger than the operate point (BOP) the output is switched on (pulled low) and is held on until mag...
