Product Information

Back to top
The HAL® 320 from Micronas is a differential Hall switch produced in CMOS technology. The sensor includes two temperature-compensated Hall plates (2.25 mm apart) with active offset compensation, a differential amplifier with a Schmitt trigger, and an open-drain output transistor. 
 
The HAL 320 Differential Sensor responds to spatial differences of the magnetic field. The Hall voltages at the two Hall plates, S1 and S2, are amplified with a differential amplifier. The differential signal is compared with the actual switching level of the internal Schmitt trigger. Accordingly, the output transistor is switched on or off. The sensor has a bipolar switching behavior and requires positive and negative values of B = BS1 - BS2 for correct operation. 
 
The sensor is designed for industrial and automotive applications and operates with supply voltages from 4.5 V to 24 V in the ambient temperature range from –40 °C up to 150 °C. The HAL 320 is an ideal sensor for target wheel applications, ignition timing, anti-lock brake systems, and revolution counting in extreme automotive and industrial environments.
 
The HAL 320 is available in the SMD-package SOT89B-2 and in the leaded versions TO92UA-3 and TO92UA-4.
 

Features

Back to top
Distance between Hall plates: 2.25mm
Operates from 4.5V to 24V supply voltage
Switching offset compensation at 62KHz
Overvoltage protection
Operates with magnetic fields from DC to 10 KHz
Short-circuit protected open-drain output by thermal shutdown
Reverse-voltage protection at V DD-pin
Output turns low with magnetic south pole on branded side of package and with a higher magnetic flux density in sensitive area S 1 as in S 2
On-chip temperature compensation circuitry minimizes shifts of the magnetic parameters over temperature and 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 hysteresis
EMC corresponding to ISO7637
