UHS41
DESCRIPTION
The UTC UHS41 is an integrated Hall effect latched sensor designed for electronic mutation of brush-less DC motor applications. The device includes a voltage regulator, reverse battery protection diode, Hall sensor with dynamic offset cancellation system, temperature pensation circuitry, small signal amplifier, Schmitt trigger and an open-collector output to sink up to 25m A.
These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, 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. It also can be used for Automotive, Consumer and Industrial, Solid-state switch, Speed...
