HAL3725UP-A-2-A-2-00

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.
