AH3572-P-B

AH3572 HIGH VOLTAGE HIGH SENSITIVITY HALL EFFECT OMNIPOLAR SWITCH Description Pin Assignments The AH3572 is a high voltage high sensitivity Hall Effect Omnipolar (TOP View) switch IC designed for proximity, position and level sensing in consumer home appliances, office equipment, smart home to 3 OUTPUT industrial applications. To support wide range of demanding GND 2 applications, the design has been optimized to operate over the 1 VDD supply range of 3.0V to 28V. With chopper stabilized architecture and NEW PRODUCT an internal bandgap regulator to provide temperature compensated SOT23 supply for internal circuits, the AH3572 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 (Front View) supply. The output has an over current limit and a Zener clamp... 3. OUTPUT The single open drain output can be switched on with South or North 2. GND pole of sufficient strength. When the magnetic flux density (B) 1. VDD perpendicular to the package is larger than the operate point (BOP) the output is switched on (pulled low) and is held on until magnetic flux SIP-3 (Bulk Pack) density B is lower than the release point (BRP).
