FEATURES
• Linear output for circuit design flexibility
• Quad-Hall IC design minimizes mechanical stress effects
• Responds to either positive or negative Gauss
• Uses 7 mA at 5 Vdc for energy efficiency
• Single current sinking or current sourcing output
• Rail-to-rail operation provides more usable signal for higher
accuracy
• Temperature-compensated magnetics help provide stable
operation over a wide temperature range of -40°C to 150°C
[-40°F to 302°F]

DESCRIPTION
The SS490 Series are small, versatile, linear Hall-effect
devices which are operated by the magnetic field from a
permanent magnet or an electromagnet. The ratiometric
output voltage is set by the supply voltage and varies
in proportion to the strength of the magnetic field. The
integrated circuitry provides increased temperature stability
and sensitivity. Laser-trimmed, thin film resistors provide high
accuracy (null to ±%, sensitivity up to ±3%) and temperature
compensation. They respond to either positive or negative
Gauss, monitoring either or both magnetic poles. The quad
Hall sensing element minimizes the effects of mechanical
or thermal stress on the output. The positive temperature
coefficient of the sensitivity (+0.02%/°C typical) helps
compensate for the negative temperature coefficients of
low-cost magnets, providing a robust design over a wide
temperature range. Rail-to-rail operation (over full voltage
range) provides a more usable signal for higher accuracy.
These products have an operating temperature range of
-40°C to 150°C [-40°F to 302°F], appropriate for industrial
and automotive environments. The SS490B versions
offer cost-effective sensing solutions with wider null and
sensitivity tolerances, and a wider drift over temperature than
the SS490A higher performance products. Both the SS490A
and SS490B versions have a typical sinking or sourcing
output of 1.5 mA continuous, use 7 mA supply current at 5.0 V
at 25°C [77°F], and provide predictable performance over the
full temperature range. For design flexibility, these products
are available in the following flat TO-92 package styles:

• Anti-tampering magnetic field sensor in smart remote utility
meters
• Pump control in heavy-duty equipment and household
appliances
• Simple linear or angular displacement sensing
• Handlebar/throttle position sensing in e-bikes and scooters
• Current sensing in appliances
• Speed adjustment trigger in tools and appliances
• Magnetic code reading in safes, security and building
access control systems

NOTICE
Absolute maximum ratings are the extreme
limits the device will momentarily withstand
without damage to the device. Electrical and
mechanical characteristics are not guaranteed
if the rated voltage and/or currents are
exceeded, nor will the device necessarily
operate at absolute maximum ratings.

magnetic characteristics. To test the switch
against the specified limits, the switch must
be placed in a uniform magnetic field.
