AH3582 HIGH VOLTAGE HIGH SENSITIVITY HALL EFFECT OMNIPOLAR WITH INTERNAL PULL UP RESISTOR Description Pin Assignments The AH3582 is a high voltage high sensitivity Hall Effect Omnipolar (TOP View) switch IC designed for proximity, position and level sensing in industrial and consumer home appliances and personal care 3 OUTPUT applications. To support wide range of demanding applications, the GND 2 design has been optimized to operate over the supply range of 3.0V 1 V DD to 28V. With chopper stabilized architecture and an internal bandgap regulator to provide temperature compensated supply for internal SOT23 circuits, the AH3582 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 (TOP View) has an over current limit and a Zener clamp. 3. OUTPUT The internally pulled-up output can be switched on with either South 2. GND or North pole of sufficient strength. When the magnetic flux density 1. V DD (B) perpendicular to the package is larger than the operate point (B ) the output is switched on (pulled low) and is held on until SIP-3 (Bulk Pack) OP magnetic flux density B is lower than the release point (B ).
