Hall Switch Unipolar Inverted Medium Sensitivity SOT89

Manufacturer:  

Micronas

MFG Part #:  

HAL518SF-A-4-R-1-00

Part #:  
HAL518SF-A
Family:   HAL 5xy
Availability   Short Lead Time
RoHS Status:   Available RoHS Compliant
The HAL5xx family consists of different Hall switches produced in CMOS technology. All sensors include a temperature-compensated Hall plate with active offset compensation, a comparator, and an open-drain output transistor. The comparator compares the actual magnetic flux through the Hall plate (Hall voltage) with the fixed reference values (switching points). Accordingly, the output transistor is switched on or off. The sensors of this family differ in the switching behavior and the switching points. The active offset compensation leads to constant magnetic characteristics over supply voltage and temperature range. In addition, the magnetic parameters are robust against mechanical stress effects. The sensors are designed for industrial and automotive applications and operate with supply voltages from 3.8 V to 24 V in the ambient temperature range from –40 °C up to 150 °C. All sensors are available in the SMD-package SOT89B-1 and in the leaded versions TO92UA-1 and TO92UA-2.
Features 
  • switching offset compensation at typically 62 kHz
  • operates from 3.8 V to 24 V supply voltage
  • overvoltage protection at all pins
  • reverse-voltage protection at VDD-pin
  • magnetic characteristics are robust regarding mechanical stress effects
  • short-circuit protected open-drain output by thermal shut down
  • operates with static magnetic fields and dynamic magnetic
  • constant switching points over a wide supply voltage range
  • the decrease of magnetic flux density caused by rising temperature in the sensor system is compensated by a built-in negative temperature coefficient of the magnetic characteristics
  • EMC corresponding to DIN 40839
