SS2019

SS2019 Hall Latch Position Sensor Features and Benefits – 4.5V to 24V Operation – -40°C to 150°C Superior temperature operation – Bipolar technology – Open-collector 25 mA output – Reverse battery protection – Small Size SOT23 3L or SIP 3L – Solid-state reliability – Resistant to physical stress – Activate with small, commercially available permanent magnets Application Examples – Brushless DC motor commutation – Automotive, Consumer and Industrial – Solid-state switch – Speed measurement – Revolution counting – Angular position detection – Proximity detection 3 pin SOT23 (suffix SO) 3 pin SIP (suffix UA) Functional Block Diagram SIP Package Pin 1 – VDD Pin 2 – GND Pin 3 – OUT SOT Package Pin 1 – VDD Pin 2 – OUT Pin 3 – GND 1 V3.10 Nov 1, 2013 General Description The SS2019 is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. 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. 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 SS2019 Hall Latch Position Sensor temperature and supply voltage changes. If a magnetic flux density larger than threshold Bop, Out...
