AH3768Q pdf
Description
The AH3768Q 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 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 AH3768Q 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.

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
on (pulled low). The output is held latched until magnetic flux density
reverses and becomes lower than the release point (Brp).
