SS360NT/SS360ST/SS460S
High Sensitivity Bipolar Latching
Digital Hall-Effect Sensor ICs
DESCRIPTION
The SS360NT/SS360ST/SS460S High Sensitivity Bipolar
Latching Digital Hall-Effect Sensor ICs are small, sensitive and
versatile devices that are operated by the magnetic field from a
permanent magnet or an electromagnet. They are designed to
respond to alternating North and South poles. The SS360NT is
turned ON by a North pole while the SS360ST and SS460S
are turned ON by a South pole.
The SS360NT/SS360ST/SS460S offers reliable switching
points with a high magnetic sensitivity of 30 G typical (55 G
maximum). This sensor IC does not use chopper stabilization
on the Hall element, providing a clean output signal and a
faster latch response time when compared to competitive high
sensitivity Hall-effect bipolar latching sensor ICs which do use
chopper stabilization.
These products offer reverse polarity protection, deliver a
stable output over a -40 °C to 150 °C [-40 °F to 302 °F]
temperature range, and can accept any dc supply voltage from
3 Vdc to 24 Vdc.
FEATURES AND BENEFITS
Fastest response time in its class: Provides more
efficiency in commutating a brushless dc motor
No chopper stabilization: Results in a clean output signal
High sensitivity: Operates from only 30 Gauss typical, at
25°C [77 °F] and 55 Gauss maximum over the full -40 °C to
150 °C [-40 °F to 302 °F] temperature range, allowing for
the use of smaller, magnets or a wider air gap
Bipolar latching magnetics: Makes these products well-
suited for accurate speed sensing and RPM (revolutions per
minute) measurement
Sub-miniature, SOT-23 surface mount package
(SS360NT/SS360ST) supplied on tape and reel: Allows
for compact design with automated component placement
For brushless dc motor manufacturers that need latching
sensors with reliable, consistent performance for more efficient
and smaller designs, Honeywell’s new family of High
Sensitivity Hall-Effect Bipolar Latching Sensor ICs responds to
low magnetic fields and offers consistent repeatability while
delivering faster response times to a change in magnetic field
for better motor efficiency.
These Hall-effect devices are available in two package styles:
the SS360NT and SS360ST in the miniature SOT-23 surface
mount package and the SS460S in the leaded, flat TO-92-style
package.
The SS360NT and SS360ST are available on tape and reel
(3000 units per reel). The SS460S is available in a bulk
package (1000 units per bag).
Small, leaded, flat TO-92-style package (SS460S): Allows
for a compact PC board layout
Wide operating voltage range of 3 Vdc to 24 Vdc: Allows
for potential use in a wide range of applications
Built-in reverse voltage: Enhances the protection of the
sensor and the circuits
Durable design: Allows operation up to 150 °C [302 °F]
