Product Description:
SS551AT SS351AT SS451A Full-Range Hall Effect Digital Position
Sensor Ics
Features:
SS551AT Hall Effect digital position sensor IC, full polarity, low
sensitivity, SOT-89B, 1000 units/pocket tape and reel.
The SS551AT series of low-cost bipolar Hall effect sensor ics adopt
surface mount packaging and feature thermal balance integrated
circuits throughout the entire temperature range. Bipolar magnetic
responses alternate between the North Pole and the South Pole.
The built-in voltage stabilizer can provide very stable operation
within the power supply voltage range of 4.5Vdc to 24Vdc. The
internal circuit can prevent sensor damage and avoid unexpected
reversal of the power supply voltage polarity. The SS50AT series of
low-cost bipolar Hall effect sensors are small, multi-functional
digital Hall effect devices operated by the magnetic fields of
permanent magnets or electromagnets. The output voltage of the
collector open drain can be easily connected to various electronic
circuits.
Note: Integrated circuits offer excellent temperature stability and
accuracy in robust designs. The operating temperature range of
these digital Hall sensors is -40°C to 125°C [-40°F to 257°F],
making them suitable for commercial, consumer and industrial
environments.
