Hall Latch Position Sensor
General Description
The SS41F is an integrated Hall effect latched sensor
designed for electronic commutation of brush-less
DC motor applications. The device integrates a
voltage regulator, reverse battery protection diode,
Hall sensor with dynamic offset cancellation system,
temperature compensation circuitry, small signal
amplifier, Schmitt trigger and an open-collector
output to sink up to 25 mA.
temperature and supply voltage changes. If a mag-
netic flux density larger than threshold Bop, Output
is turned on (low). The output state is held until a
magnetic flux density reversal falls below Brp,
causing Output to be turned off (high).
Thanks to its wide operating voltage range and ex-
tended choice of temperature range, it is quite suita-
ble for use in DC motor applications.
These Hall-effect switches are monolithic integrated
circuits with tighter magnetic specifications, de-
signed to operate continuously over extended tem-
peratures to +150°C,and are more stable with both
The device is delivered in a Small Outline Transistor
(SOT) or in a Plastic Single In Line (SIP 3L flat).
Both 3-lead packages are RoHS compliant.

Restriction of Hazardous Substances
Operating Point (BOP)
Magnetic flux density applied on the branded side of the package which turns the
output driver ON (VOUT = VDSon
)
Release Point (BRP)
Magnetic flux density applied on the branded side of the package which turns the
output driver OFF (VOUT = high)

The SOT-23 device is reversed from the UA package. The SOT-23 output transistor will be turned on(drops low) in the presence of a
sufficiently strong North pole magnetic field applied to the marked face and turned off(hoists high) in the presence of a sufficiently
strong South pole magnetic field.
