General

Descriptions

The SS119 is a unipolar Hall-effect sensor IC fab-

ricated from bipolar technology. The device inte-

grates a voltage regulator, reverse battery protec-

tion diode, Hall sensor with dynamic offset can-

cellation system, temperature compensation cir-

cuitry, small signal amplifier, Schmitt trigger and

an open-collector output to sink up to 25 mA.

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 uni-

polar switching characteristic makes these devices

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.
