AH1714 Datasheet | Diodes Incorporated

Description The AH1711/AH1712/AH1713/AH1714 is a low-voltage, highsensitivity Hall effect latch IC designed for brushless DC-motor mutation speed measurement, angular or linear encoders and position sensors in industrial applications. To support a wide range of demanding applications, the design is optimized to operate at 2.4V to 5.5V. With chopper stabilized architecture and an internal bandgap regulator to provide temperature pensated supply for internal circuits, the device provides a reliable solution over the whole operating range. The open-drain output of AH1711/AH1712/AH1713 can be switched on when applying South pole with sufficient magnetic near the top of the package, while North pole with sufficient magnetic strength causes the open-drain output switched off (AH1714 polarity inverted). When the magnetic flux density (B) perpendicular to the package is larger than the operate point (Bop) the output is switched on (pulled low). The output is held latched until magnetic flux density reverses and bees lower than the release point (Brp).
