SS360NT/SS360ST/SS460S

High Sensitivity Bipolar Latching
Digital Hall-Effect Sensor ICs

FEATURES AND BENEFITS

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.

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]
RoHS-compliant material meets Directive 2002/95

NOTICE

Bipolar Hall-effect sensor ICs may have an initial output in either the ON or OFF state if powered up with an applied magnetic
field in the differential zone (applied magnetic field >Brp and <Bop). Honeywell recommends allowing 10 µs for output voltage to
stabilize after supply voltage has reached its final rated value.

NOTICE

The magnetic field strength (Gauss) required to cause the switch to change state (operate
and release) will be as specified in the magnetic characteristics. To test the switch against
the specified magnetic characteristics, the switch must be placed in a uniform magnetic
field.

Note 1: Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the

electrical and mechanical characteristics are not guaranteed as the maximum limits (above recommended operating conditions)
are approached, nor will the device necessarily operate at absolute maximum ratings.
