Q
HIGH-VOLTAGE, MEDIUM-SENSITIVITY
AUTOMOTIVE HALL- EFFECT LATCH
Description
Pin Assignments
The AH3766Q is an AEC-Q100 qualified high-voltage, mediumsensitivity Hall-Effect latch IC designed for brushless DC-motor
commutation, speed measurement, angular or linear encoders and
position sensors in automotive applications. To support 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 AH3766Q 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 overcurrent limit and a Zener clamp.

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

5. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
6. The absolute maximum VDD of 32V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to
operate the device at the absolute maximum rated conditions for any period of time.

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.
