HALÂ® 37xy

Second-Generation 3D HALÂ® Sensor Family

with Superior Angular Accuracy

The HAL 37xy family is the second sensor

generation using Micronasâ proprietary

3D HAL technology, which offers a further

improvement of the angular performance.

Compared to the first generation, a 30%

lower angular error has been achieved.

Operation with magnetic fields down to

ï±20 mT is enabled thanks to the improved

technology. HAL 3715 and HAL 372x pro-

vide a linear, ratiometric analog output sig-

nal with integrated wire-break detection

working with pull-up or pull-down resistors.

HAL 373x features digital output formats

such as PWM and SENT SAEJ2716 rev.

2010. The digital output format is customer

programmable.

The sensors can measure three magnetic

field components BX, BY, and BZ. This

enables a set of potential applications for

position detection, such as wide distance,

angle or through-shaft angular measure-

ments. On-chip signal processing calcu-

lates the angle out of two of the magnetic

field components and converts this value

into an output signal. The sensor exhibits

excellent drift performance over the specified

temperature range resulting in a new class

of accuracy for angular or linear measure-

ments. The sensor features an arbitrarily

programmable stepwise linear characteris-

tic for linearization of the output signal.

Major characteristics can be adjusted to the

magnetic circuit by programming the non-

volatile memory.

The sensors contain advanced on-board

diagnostic features that enhance fail-safe

detection. The devices are designed for

automotive and industrial applications and

operate in the junction temperature range

from ï40 Â°C up to 170 Â°C. The sensors are

available in a very small four-pin leaded

transistor package TO92UP, as well as in a

SOIC8 package.
