General Description

The SS41 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.

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

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.
