AH3764Q Q HIGH-VOLTAGE, HIGH-SENSITIVITY AUTOMOTIVE HALL-EFFECT LATCH PRELIMINARY - CONFIDENTIAL Description Pin Assignments The AH3764Q is an AEC-Q100 qualified high-voltage, high-sensitivity Hall-Effect latch IC designed for brushless DC-motor commutation, speed measurement, angular or linear encoders and position sensors in automotive applications. To support a wide range of demanding applications, the design is 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 AH3764Q 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. (Top View) 3 OUTPUT GND 2 1 VDD SC59 and SOT23 The single, open-drain 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 package is larger than the operate point (Bop) the output is switched (Top View) on (pulled low). The output is held latched until magnetic flux density reverses and becomes lower than the release point (Brp). 3. OUTPUT 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 south pole to the non-part marking side. 1. VDD 2.
