FEATURES AND BENEFITS ( = competitive differentiator)
Energy efficient: Supply voltage as low as 2.2 Vdc,
combined with very low average current (1.8 µA typ. for
SL353LT the lowest in its class), reduces power
consumption, provides extended battery life, and promotes
energy efficiency
Push-pull output does not require external pull-up
resistor: Simplifies interface with common electrical circuits
and potentially reduces PC board space and costs to the
customer
Non-chopper stabilized design: Does not utilize chopper
stabilization, eliminating the noise generated by products
using this technique. This means that customers do not
need filters to compensate for the noise, helping to reduce
PC board space, part counts, and costs for the application
Versatile: Omnipolar capability with high and low duty
cycle options allows for use in a variety of potential
applications with low power requirements and/or battery
operation, including motion control, lid closure detection,
presence-absence, metering, and displacement sensing
Stable: Thermally balanced integrated circuit provides for
stable operation over a wide temperature range, from -40°
to 85 °C [-40° to 185 °F]
Subminiature size: The SOT-23 subminiature package
size requires less PCB space, allowing for use in smaller
assemblies
Price competitive: By using BiCMOS technology,
Honeywell has been able to design a reduced size
integrated circuit, saving on manufacturing costs while still
meeting customer requirements; these savings can result in
lower costs to customers
Helps reduce total system cost: Because they can be
operated by a North pole or a South pole, they do not
require the magnet polarity to be identified, thus making the
installation easier and potentially reducing the system cost
Reduces manufacturing costs: SL353 Series is supplied
on tape and reel, often allowing for automated, lower-cost
pick and place assembly which can help the customer
reduce manufacturing costs
Supplied on tape and reel: Allows for a compact design
with automated component placement, helping to reduce
manufacturing costs
Compliant: RoHS-compliant materials meet Directive
2002/95/EC
