General Description

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 sen-

sor with dynamic offset cancellation system, temper-

ature compensation circuitry, small signal amplifier,

Schmitt trigger and an open-collector output to sink

up to 25 mA

SIP Package

Pin 1 – V_DD

Pin 2 – GND

Pin 3 – OUT

SOT Package

Pin 1 – V_DD

Pin 2 – OUT

Pin 3 – GND

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to op-

erate 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 B_RP, 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.
