Unipolar Hall-Effect Digital Switch 1 V2.10 Ma y 1, 20 12 Packages Features and Benefits 3 pin SOT23 (suffix SO) 3 pin SIP (suffix UA) – 4.5V to 24V Operation – -40°C to 150°C Superior temperature operation – Bipolar technology – Open-collector 25 mA output – Reverse battery protection – Solid-state reliability – Resistant to physical stress – Small Size-SOT23 3L or SIP 3L – Activate with small, commercially available Permanent magnets Functional Block Diagram Application Examples – Automotive, Consumer and Industrial – Solid-state switch – Brushless DC motor commutation – Speed detection – Angular position detection – Linear position detection – Proximity detection General Description The SS129 is a uni polar 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 25 mA. 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 °C, 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 oper ating 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 ( SIP 3L flat). Both 3-lead packages are RoHS compliant.
