S1104 Unipolar Hall Switch-Low Sensitivity

¨C        both RoHS compliant packages

General  Descriptions

The S1104 is a uni¬polar Hall-effect sensor IC fabricated from CMOS technology. The device integrates a voltage regulator, Hall sensor with dynamic offset cancellation 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 operate continuously over extended temperatures to +150¡æ,and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet.

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) and in a Plastic Single In Line (TO-92 flat). Both 3-lead packages are RoHS compliant.
