UHS41 Datasheet
 HALL-EFFECT LATCHED SENSOR

 

 

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.
