General Description
The SS3613 Omnipolar Hall effect sensor IC is fab-
ricated from mixed signal CMOS technology .It in-
corporates advanced chopper-stabilization techniques
to provide accurate and stable magnetic switch points.
The circuit design provides an internally controlled
clocking mechanism to cycle power to the Hall ele-
ment and analog signal processing circuits. This
serves to place the high current-consuming portions
of the circuit into a “Sleep” mode. Periodically the
device is “Awakened” by this internal logic and the
magnetic flux from the Hall element is evaluated
against the predefined thresholds. If the flux density
is above or below the Bop/Brp thresholds then the
output transistor is driven to change states according-
ly. While in the “Sleep” cycle the output transistor is
latched in its previous state. The design has been op-
timized for service in applications requiring extended
operating lifetime in battery powered systems.
The output transistor of the SS3613 will be latched on
(Bop) in the presence of a sufficiently strong South or
North magnetic field facing the marked side of the
package. The output will be latched off (Brp) in the
absence of a magnetic field.

Typical Application Circuit
SEC's pole-independent sensing technique allows for
operation with either a north pole or south pole mag-
net orientation, enhancing the manufacturability of the
device. The state-of-the-art technology provides the
same output polarity for either pole face.
capacitor be connected (in close proximity to the Hall
sensor) between the supply and ground of the device
to reduce both external noise and noise generated by
the chopper-stabilization technique. This is especially
true due to the relatively high impedance of battery
supplies.
It is strongly recommended that an external bypass

CMOS Hall IC Technology
The chopper stabilized amplifier uses switched capacitor techniques to eliminate the amplifier offset voltage,
which, in bipolar devices, is a major source of temperature sensitive drift. CMOS makes this advanced technique
possible. The CMOS chip is also much smaller than a bipolar chip, allowing very sophisticated circuitry to be
placed in less space. The small chip size also contributes to lower physical stress and less power consumption.
