SS41
Bipolar Hall-Effect Position Sensor
General Description
The SS41 is an integrated Hall effect latched sensor designed
for electronic commutation of brush-less DC motor
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).
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℃,and are
more stable with both temperature and supply voltage
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.
