Hall Latch Position Sensor
General Description
temperature and supply voltage changes. If a magnetic 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).
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.
Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in DC motor applications.
These Hall-effect switches are monolithic integrated
circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures 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.

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.
