AH3372 HIGH VOLTAGE HIGH SENSITIVITY HALL EFFECT UNIPOLAR SWITCH Description Pin Assignments The AH3372 is a high voltage high sensitivity Hall Effect Unipolar switch IC designed for proximity, position and level sensing in (TOP View) industrial and consumer home appliances and personal care applications. To support wide range of demanding applications, the 3 OUTPUT design has been optimized to operate over the supply range of 3.0V GND 2 NEW PRODUCT to 28V. With chopper stabilized architecture and an internal bandgap 1 VDD regulator to provide temperature compensated supply for internal circuits, the AH3372 provides a reliable solution over the whole SC59 and SOT23 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 pole of sufficient strength. When the magnetic flux density (B) perpendicular (TOP View) to the package is larger than the operate point (BOP) the output is switched on (pulled low) and is held on until magnetic flux density B is 3. OUTPUT lower than the release point (BRP). The output remains switched off for 2. GND North pole fields to or no magnetic fields. 1. VDD SIP-3 (Bulk Pack) The magnetic operating and release polarity is opposite for SOT23 and SC59 packages. The SOT23 and SIP-3 (Ammo Pack), SIP-3 (Bulk Pack) packages require south pole to the part marking side to operate while SC59 requires south pole to the non-part marking side.
