AH3582
HIGH VOLTAGE HIGH SENSITIVITY HALL EFFECT
OMNIPOLAR WITH INTERNAL PULL_UP RESISTOR
Description
The AH3582 is a high voltage high sensitivity Hall Effect Omnipolar
switch IC designed for proximity, position and level sensing in
industrial and consumer home appliances and personal care
applications. To support wide range of demanding applications, the
design has been 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 AH3582 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 internally pulled-up output can be switched on with either South
or 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) and is held on until
magnetic flux density B is lower than the release point (BRP).
