The HAL 37xy family is the second sensor generation using Micronas’ 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.
HAC 37xy features integrated capacitors for improved electromagnetic compatibility (EMC) and PCB-less applications. It is available in the TO92UF package.
HAR 37xy is the dual-die version of the HAL 37xy family. It is available in the same SOIC8 package as of HAL 37xy. Each sensor provides true redundancy as it consists of two independent dies stacked in a single package. The stacked-die architecture ensures that both dies sense the same magnetic field position, thus generating synchronous measurement outputs.
Operation
with magnetic fields down to ±20 mT is enabled thanks to the improved
technology. HAL 3715 and HAL 372x provide a linear, ratiometric analog
output signal 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 B X, BY, and BZ.
This enables a set of potential applications for position detection,
such as wide distance, angle or through-shaft angular measurements.
On-chip signal processing calculates 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 measurements. The sensor features an arbitrarily programmable
stepwise linear characteristic 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 −40 °C up to 170 °C. The
sensors are available in a very small four-pin leaded transistor package
TO92UP, as well as in a SOIC8 package.
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
conditioning 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 measurements 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
calibration 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 modulating the output voltage. No additional programming pin is needed.
