HIGH VOLTAGE HIGH SENSITIVITY
HALL EFFECT OMNIPOLAR SWITCH
Description
Pin Assignments
The AH3574 is a high voltage high sensitivity Hall Effect Omnipolar
switch IC designed for proximity, position and level sensing in
consumer home appliances, office equipment, smart home to
industrial 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 AH3574 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.

Notes:
5. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
6. The absolute maximum VDD of 32V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to
operate the device at the absolute maximum rated conditions for any period of time.

Notes:
7. When power is initially turned on, VDD must be within its correct operating range (3.0V to 28V) to guarantee the output sampling. The output state is valid
after the start-up time of 10µs typical from the operating voltage reaching 3V.
8. Typical values are defined at TA = +25°C , VDD = 12V. Maximum and minimum values over the operating temperature range is not tested in production but
guaranteed by design, process control and characterization.
9. Guaranteed by design, process control and characterization. Not tested in production.
10. The device will limit the output current IOUT to current limit of IOCL.
