SS400 Series
DESCRIPTION
The SS400 Series sensor ICs are small, versatile, digital Hall-
effect devices that are operated by the magnetic field from a
permanent magnet or an electromagnet, and are designed to
respond to alternating North and South poles or to a South
pole only. Bipolar, latching and unipolar magnetics are
available.
Band gap regulation provides stable operation over 3.8 Vdc to
30 Vdc supply voltage range. These sensors are capable of
continuous 20 mA sinking output and may be cycled as high as
50 mA max. Its 3.8 V capability allows for use in many potential
low voltage applications.
The digital, open collector sinking-type output is easily
interfaced with a wide variety of electronic circuits.
To provide reliable products and consistent quality, the SS400
Series are tested at both 25 °C [75 °F] and 125 °C [257 °F]. All
catalog listings in this series are qualified for operation up to
150 °C [302 °F].
For design flexibility, the lead and packaging options are:
Straight leads, 14,99 mm [0.59 in] long, in bulk or
ammopak tape-in-box packaging
Straight leads, 18,7 mm [0.735 in] long, in bulk packaging
Formed leads, 14,99 mm [0.59 in] long, in bulk or
ammopak tape-in-box packaging
Please refer to SS400 Series Order Guide on page 7 for
details.
