General Description

Hall

Plate

The SS1332 is a unipolar Hall-effect sensor IC fabri-

cated from CMOS technology. The device integrates a

voltage regulator, Hall sensor with dynamic offset can-

cellation system, small signal amplifier, Schmitt trigger

and an open-drain output driver. With suitable output

pull up, they can be used with bipolar or CMOS logic

circuits.

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to oper-

ate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply volt-

age changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod mag-

net.

Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in

automotive, industrial and consumer applications.

The device is delivered in a Small Outline Transistor (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

Automotive and Harsh, Noisy Environments Three-Wire Circuit

Application Comments

For proper operation, a 100nF bypass capacitor should be placed as close as possible to the device between the V_DD

and ground pin.

For reverse voltage protection, it is recommended to connect a resistor or a diode in series with the V_DDpin.

When using a resistor, three points are important:

- the resistor has to limit the reverse current to 50mA maximum (V_CC/ R1 ≤ 50mA)

- the resulting device supply voltage V_DDhas to be higher than V_DDmin (V_DD= V_CC– R1.I_DD)

- the resistor has to withstand the power dissipated in reverse voltage condition (P_D= V_CC²/ R1)

When using a diode, a reverse current cannot flow and the voltage drop is almost constant (≈ 0.7V).

Therefore, a 100 Ω /0.25W resistor for 5V application and a diode for higher supply voltage are recommended. Both

solutions provide the required reverse voltage protection.

When a weak power supply is used or when the device is intended to be used in noisy environment, it is recom-

mended the second figure above is used.

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 V_DD. The diode D1 provides additional 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.
