Unipolar Hall Switch
General Description
The SS5682 is a unipolar Hall effect sensor IC fabri-
cated from mixed signal CMOS technology. The de-
vice integrates a voltage regulator, Hall sensor with
dynamic offset cancellation system, Schmitt trigger
and an open-drain output driver, all in a single pack-
age.
Hall Electronic Device - in addition to those listed
above. Thanks to its wide operating voltage range and
extended choice of temperature range, it is quite suita-
ble for use in automotive, industrial and consumer ap-
plications.
The device is delivered in a Small Outline Transistor
(SOT) for surface mount process or in a Plastic Single
In Line (SIP flat) for through- hole mount. Both 3-lead
packages are RoHS compliant.
It incorporates advanced chopper stabilization tech-
niques to provide accurate and stable magnetic switch
points. There are many applications for this HED –

Unique Features
Based on mixed signal CMOS technology, SS5682 is a Hall-effect device with high magnetic sensitivity. This
multi-purpose latch meets most of the application requirements.
The chopper-stabilized amplifier uses switched capacitor technique to suppress the offset generally observed with
Hall sensors and amplifiers. The CMOS technology makes this advanced technique possible and contributes to
smaller chip size and lower current consumption than bipolar technology. The small chip size is also an important
factor to minimize the effect of physical stress. This combination results in more stable magnetic characteristics
and enables faster and more precise design.
The wide operating voltage from 2.5V to 24V, low current consumption and large choice of operating tempera-
ture range according to “L”, “K”and “E” specifications make this device suitable for automotive, industrial and
consumer applications.

The SOT-23 device is reversed from the UA package. The SOT-23 output transistor will be turned on(drops low) in the presence of a
sufficiently strong South pole magnetic field applied to the marked face.
Application Information
It is strongly recommended that an external bypass capacitor be connected (in close proximity to the Hall sensor)
between the supply(VDD Pin) and ground(GND Pin) of the device to reduce both external noise and noise gener-
ated by the chopper stabilization technique. As is shown in the following figure, a 0.1μF capacitor is typical.
For reverse voltage protection, it is recommended to connect a resistor or a diode in series with the VDD pin.
When using a resistor, three points are important:
- the resistor has to limit the reverse current to 50mA maximum (VCC / R1 ≤ 50mA)
- the resulting device supply voltage VDD has to be higher than VDD min (VDD = VCC – R1*IDD
- the resistor has to withstand the power dissipated in reverse voltage condition (P = VCC
)
2/R1)
D
When using a diode, a reverse current cannot flow and the voltage drop is almost constant (≈0.7V).
Therefore, a 100Ω/0.25W resistor for 5V application and a diode for higher supply voltage are recommended.
Typical Three-Wire Application Circuit
When a weak power supply is used or when the device is intended to be used in noisy environment, it is
recommended that following figure is used.

Automotive and Severe Environment Protection Circuit
The low-pass filter formed by R1 and C1 and the Zener diode Z1 bypass the disturbances or voltage spikes
occurring on the device supply voltage VDD. The diode D1 provides additional reverse voltage protection.
Both solutions provide the required reverse voltage protection.
ESD Precautions
Electronic semiconductor products are sensitive to Electro Static Discharge (ESD).
Always observe Electro Static Discharge control procedures whenever handling semiconductor products.
