DESCRIPTION
The VF360NT, VF360ST, and VF460S High Sensitivity
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 VF360NT
is turned ON by a North pole, while the VF360ST and VF460S
are turned ON by a South pole. 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 latching sensor ICs
which do use chopper stabilization.
VALUE TO CUSTOMERS
• AEC-Q100 qualification provides enhanced reliability and
quality of electronic components. Components meeting
these specifications are often suitable for use in harsh
automotive environments without the customer’s need for
additional component-level qualification testing.
• Designed to provide reliable, consistent performance and
a fast response time, enhancing efficiency in brushless dc
motor (BLDC) applications
• Designed to provide a wide supply voltage range and no
chopper delay, allowing for potential use in a variety of
applications
• Designed to provide a clean output signal without the
customer having to include additional circuitry to achieve
noise suppression due to chopper stabilization
DIFFERENTIATION
Honeywell’s VF360NT, VF360ST, and VF460S AEC-Q100qualified latching sensor ICs offer better performance
than many competitive sensor ICs that employ chopper
stabilization techniques.
• Response time: Honeywell’s device provides a fast
response time, enabling efficiency in BLDC motors.
• No noise generation: Honeywell’s device utilizes a resistorcapacitor (RC) circuit to enable noise suppression required
for chopper stabilized sensors.

NOTICE
These 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 after supply
voltage has reached 5 V (VF360NT,
VF360ST) or 3 V (VF460S) for the output
voltage to stabilize.
CAUTION
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 limits, the switch
must be placed in a uniform magnetic
field.
