AH3769Q

PRELIMINARY - CONFIDENTIAL Description The AH3769Q 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 AH3769Q 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.
