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.

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).

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

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
