Major Applications
Available Types and Behavior
The new HAL 37xy family is the optimal
system solution for applications, such as:
◆ Linear movement measurements
(EGR, clutch, transmission position)
◆ Rotary position measurements
(gear selector, motor air management)
◆ Non-contact potentiometer

System Architecture
The sensors include two vertical and one
horizontal Hall plate with spinning current
offset compensation for the detection of X,
Y, or Z magnetic field components, a signal
processor for calculation and signal condi-
tioning of two magnetic field components,
protection devices, and a ratiometric linear
analog, PWM, or SENT output.
The spinning current offset compensation
minimizes the errors due to supply voltage
and temperature variations or external
package stress.
The signal path of HAL 37xy consists of two
channels (CH1 and CH2). Depending on
the product variant, two out of the three
magnetic field components are connected
to Channel 1 and Channel 2.
The sensors can be used for angle mea-
surements in a range between 0° and 360°
(end-of-shaft and through-shaft setup), as
well as for robust position detection (linear
movement or position). The in-system cali-
bration can be utilized by the system
designer to optimize the performance for a
specific system. The calibration information
is stored in the on-chip EEPROM.

The HAL 37xy is programmable by modu-
lating the output voltage. No additional pro-
gramming pin is needed.
