UHS41

DESCRIPTION

The UTC UHS41 is an integrated Hall effect latched sensor 

designed for electronic commutation of brush-less DC motor 

applications. The device includes 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 25mA. 

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 measurement, Revolution 

counting, Angular position detection and Proximity detection.
