SS360PT/SS460P
High Sensitivity Latching Digital
Hall-Effect Sensor ICs with Built-in
Pull-up Resistor
DESCRIPTION
These products offer reverse polarity protection, deliver a stable
The SS360PT/SS460P High Sensitivity Latching Hall-Effect
Sensor ICs with Built-in Pull-up Resistor 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 SS360PT
is activated by a North pole while the SS460P is activated by a
South pole.
output over a -40 °C to 125 °C [-40 °F to 257 °F] temperature
range, and can accept a dc supply voltage from 3 Vdc up to 24
Vdc (see specifications below for details).
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 Latching Sensor ICs with Built-in Pull-up resistor responds
to low magnetic fields and offers repeatable operation while
delivering faster response times to a change in magnetic field for
better motor efficiency.
The SS360PT/SS460P 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
SS360PT in the miniature SOT-23 surface mount package and
the SS460P in the leaded, flat TO-92-style package.
The internal pull-up resistor often eliminates the need for external
components, helping to reduce the system cost. These high-
performance yet economical sensor ICs are well suited for
demanding, cost-sensitive high-volume applications.
The SS360PT is supplied on tape and reel (3000 units per reel).
The SS460P 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
• Sub-miniature, SOT-23 surface mount package (SS360PT)
supplied on tape and reel: Allows for compact design with
automated component placement
• 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
125 °C [-40 °F to 257 °F] temperature range, allowing for the
use of smaller, magnets or a wider air gap
• Small, leaded, flat TO-92-style package (SS460P): 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
• Internal pull-up Hall IC design: Simplifies installation and
helps reduce component count and system cost
• Bipolar latching magnetics: Makes these products well-
suited for accurate speed sensing and RPM (revolutions per
minute) measurement
• Built-in reverse voltage capability: Enhances the protection
of the sensor and the circuits
• Robust design: Allows operation up to 125 °C [257 °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 normal operating 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 ap-
proached, nor will the device necessarily operate at absolute maximum ratings.
