The HAL11x family consists of different Hall switches produced in CMOS technology.

All sensors include a temperature-compensated Hall plate, 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. The sensors are designed for industrial and automotive applications and operate with supply voltages from 4.5 V to 24 V in the ambient temperature range from –40 °C up to 125 °C.

All sensors are available in an SMD-package (SOT-89B) and in a leaded version (TO-92UA).

Features

– operates from 4.5 V to 24 V supply voltage

– overvoltage protection

– reverse-voltage protection at VDD-pin

– short-circuit protected open-drain output by thermal shut down

– operates with static magnetic fields and dynamic magnetic fields up to 20 kHz

– stable 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
