Description
General part information
AH3978Q Series
The AH3975Q/AH3976Q/AH3977Q/AH3978Q is an AEC-Q100 qualified high voltage dual Hall-effect sensor designed for the applications that require accurate speed and direction sensing. To support wide range of demanding applications, the design has been optimized to operate over the supply range of 2.7V to 27V. With chopper stabilized architecture and an internal bandgap regulator to provide temperature compensated supply for internal circuits, the AH3975Q/AH3976Q/AH3977Q provides speed and direction outputs, while AH3978Q provides two independent outputs at Q1 and Q2.
