Unipolar Hall-Effect Digital Switch

General Description

The SS133 is a unipolar Hall-effect sensor IC fabricated

from bipolar technology. The device integrates a voltage

regulator, reverse battery protection diode, Hall sensor with

dynamic offset cancellation system, temperature

compensation circuitry, small signal amplifier, Schmitt

trigger and an open-collector output to sink up to 50 mA.

With suitable output pull up, they can be used with bipolar

or CMOS logic circuits.

more stable with both temperature and supply voltage

changes. Internal compensation characteristic makes the

sensitivity increase slightly with temperature increasing, so

that this IC is Particularly suitable to be used with the

commonly low-cost magnets. If a magnetic flux density

larger than threshold Bop, Output is turned on (low). When

a magnetic flux density reversal falls below Brp, Output will

be turned off (high).

These Hall-effect switches are monolithic integrated circuits

with tighter magnetic specifications, designed to operate

continuously over extended temperatures to +150°C,and are

Thanks to its wide operating voltage range,extended choice

of temperature range and high reliability, it is quite suitable

for use in automotive, industrial and consumer applications.
