General Description
SIP Package
Pin 1 – VDD
Pin 2 – GND
Pin 3 – OUT
The SS539 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
SOT Package
Pin 1 – VDD
Pin 2 – OUT
Pin 3 – GND
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 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).
Thanks to its wide operating voltage range and extended choice of temperature range, it is quite suitable for use in
DC motor applications.
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.

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.
