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.
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.
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 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).
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
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]
RoHS-compliant material meets Directive 2002/95
Sub-miniature, SOT-23 surface mount package
(SS360NT/SS360ST) supplied on tape and reel: Allows
for compact design with automated component placement
