AH3782 HIGH-VOLTAGE, HIGH-SENSITIVITY HALL EFFECT LATCH WITH INTERNAL PULL-UP RESISTOR PRELIMINARY - CONFIDENTIAL Description Pin Assignments The AH3782 is a high-voltage, high-sensitivity Hall Effect latch IC with internal pull-up resistor designed for commutation of brushless DC motors, flow meters, linear encoders and position sensors in industrial and consumer home appliances and personal care applications. To support a 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 AH3782 provides a reliable solution over the whole operating range. For robustness and protection, the device has a Zener clamp on the supply. The output has an overcurrent limit and a Zener clamp. (Top View) 3 OUTPUT GND 2 1 VDD SC59 and SOT23 The internally pulled-up output can be switched on with South pole of sufficient strength and switched off with North pole of sufficient strength. When the magnetic flux density (B) perpendicular to the part marking surface is larger than the operate point (BOP) the output is (Top View) switched on (pulled low). The output is held latched until magnetic flux density reverses and becomes lower than the release point (BRP). 3. OUTPUT 2. GND The magnetic operating and release polarity is opposite for SOT23 and SC59 packages. SOT23 and SIP-3 packages will require South pole to the part marking side to operate while SC59 will require North pole to the part marking side. 1.
