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.

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

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.

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.
