SS311PT, SS411P.

Bipolar magnetics • enhanced sensitivity • Built-in pull-up resistor • Low voltage: 2.7 Vdc to 7 Vdc • Subminiature package size (SS311PT) • Through-hole and surface-mount (SOT-23 and SOT- 89B) packages • Cost effective enhanced sensitivity often allows for use of smaller, less expensive magnets. Built-in pull-up resistor easily interfaces with common electronic circuits without adding external components, helping to reduce total system cost. 2.7 Vdc to 7 Vdc supply voltage range allows use in low voltage applications, promoting energy efficiency. Subminiature package size (SS311PT) allows for compact design. SS311PT is available on tape and reel for high volume, automated component placement, helping to reduce manufacturing costs. Potential applications include speed and RPM sensing, brushless dc motor commutation, tachometer, counter pickup, motor and fan control, flow-rate sensing, and robotics control.
