Unipolar Hall Switch-Low Sensitivity
General Descriptions
The SS1104 is a unipolar Hall-effect sensor IC fab-
ricated from CMOS technology. The device inte-
grates a voltage regulator, Hall sensor with dy-
namic offset cancellation system, small signal am-
plifier, Schmitt trigger and an open-drain output
driver. With suitable output pull up, they can be
used with bipolar or CMOS logic circuits.
both temperature and supply voltage changes. The
unipolar switching characteristic makes these de-
vices ideal for use with a simple bar or rod magnet.
Thanks to its wide operating voltage range and ex-
tended choice of temperature range, it is quite suit-
able for use in automotive, industrial and consumer
applications.
These Hall-effect switches are monolithic integrat-
ed circuits with tighter magnetic specifications, de-
signed to operate continuously over extended tem-
peratures to +150°C,and are more stable with
The device is delivered in a Small Outline Transis-
tor (SOT) or in a Plastic Single In Line (SIP 3L
flat). Both 3-lead packages are RoHS compliant.

Application Information
Typical Three-Wire Application Circuit
For proper operation, a 100nF bypass capacitor should be placed as close as possible to the device between the
DD and ground pin.
V
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 (PD = VCC2/ R1)
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.
Automotive and Harsh, Noisy Environments Three-Wire Circuit
When a weak power supply is used or when the device is intended to be used in noisy environment, it is recom-
mended that figure above is used.
The low-pass filter formed by R1 and C1 and the Zener diode Z1 bypass the disturbances or voltage spikes occur-
ring 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.
