UHS41

UNISONIC TECHNOLOGIES CO., LTD UHS41 Preliminary LINEAR INTEGRATED CIRCUIT 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.  FEATURES * wide operating voltage range：4.5V~24V * Wide ambient temperature range: –40°C~+125°C * Bipolar technology * Open-collector 25mA output * Reverse battery protection * Solid-state reliability * Resistant to physical stress * Activate with small, commercially available permanent magnets  ORDERING...
