AH3767Q Q HIGH-VOLTGAE, LOW-SENSITIVITY AUTOMOTIVE HALL-EFFECT LATCH PRELIMINARY - CONFIDENTIAL Description Pin Assignments The AH3767Q is an AEC-Q100 qualified high-voltage, low-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 AH3767Q 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 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) 3. OUTPUT 2. GND on (pulled low). The output is held latched until magnetic flux density reverses and becomes lower than the release point (Brp). 1.

No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant. 2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free. 3. Halogen- and Antimony-free "Green” products are defined as those which contain Bop, (Note 10 ) IDD = 5mA 7. When power is initially turned on, VDD must be within its correct operating range (3.0V to 28V) to guarantee the output sampling. The output state is valid after the start-up time of 10µs typical from the operating voltage reaching 3V. 8. Typical values are defined at TA = +25°C, VDD = 12V. Maximum and minimum values over the operating temperature range is not tested in production but guaranteed by design, process control and characterization. 9. Guaranteed by design, process control and characterization. Not tested in production. 10. The device will limit the output current IOUT to current limit of IOCL.
