HAL 5xy

Multipurpose Hall-Effect Sensor Family

The HAL 5xy family consists of different

Hall switches produced in CMOS technol-

ogy. 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). Accord-

ingly, the output transistor is switched on or

off.

Features

Major Applications

Switching offset compensation at typi-

cally 62 kHz

The HAL 5xy is the optimal system solution

for applications, such as:

Operates from 3.8 V to 24 V

supply voltage

Endposition detection

RPM measurement of motors in various

applications, such as power window

Overvoltage protection at all pins

Reverse-voltage protection at VDD-pin

Brushless DC motors

Magnetic characteristics are robust

regarding mechanical stress effects

RPM measurements in flow meters

Replacement of micro switches

The sensors of this family differ in the

switching behavior and the switching points.

Short-circuit protected open-drain out-

put by thermal shut down

Operates with static magnetic fields and

dynamic magnetic fields up to 10 kHz

The active offset compensation leads to

constant magnetic characteristics over sup-

ply voltage and temperature range. In addi-

tion, the magnetic parameters are robust

against mechanical stress effects.

Constant switching points over a wide

supply voltage range

The decrease of magnetic flux density

caused by rising temperature in the sen-

sor system is compensated by a built-in

negative temperature coefficient of the

magnetic characteristics

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.

Ideal sensor for applications in extreme

automotive and industrial environments

EMC corresponding to ISO 7637

All sensors are available in the SMD-pack-

age SOT89B-1 and in the leaded versions

TO92UA-1 and TO92UA-2.

Operates from −40 °C to 170 °C junction

temperature

System Architecture

The HAL 5xy sensors are monolithic inte-

grated circuits which switch in response to

magnetic fields. If a magnetic field with flux

lines perpendicular to the sensitive area is

applied to the sensor, the biased Hall plate

forces a Hall voltage proportional to this

field. The Hall voltage is compared with the

actual threshold level in the comparator.

Hysteresis

Control

The temperature-dependent bias increases

the supply voltage of the Hall plates and

adjusts the switching points to the decreas-

ing induction of magnets at higher tempera-

tures. If the magnetic field exceeds the

threshold levels, the open drain output

switches to the appropriate state. The built-

in hysteresis eliminates oscillation and pro-

vides switching behavior of the output with-

out bouncing.
