DATA SHEET

HAL 371x, HAL 372x, HAL 373x

On-chip signal processing calculates the angle from two of the magnetic field components

and converts this value to an output signal. Due to the measurement method, the sensor

exhibits excellent drift performance over the specified temperature range resulting in a

new class of accuracy for angular or linear measurements.

Additionally to the built-in signal processing, the sensor features an arbitrary programm-

able linear characteristic for linearization of the output signal (with up to 33 setpoints).

Major characteristics like gain and temperature dependent offset of X/Y- and Z-channel,

reference position, phase shift between X/Y- and Z-signal, hysteresis, low-pass filter

frequency, output slope, and offset and clamping levels can be adjusted to the magnetic

circuitry by programming the non-volatile memory.

The sensors contain advanced on-board diagnostic features that enhance fail-safe detec-

tion. In addition to standard checks, such as overvoltage and undervoltage detection and

wire break, internal blocks such as ROM and signal path are monitored during normal

operation. For devices with a selected PWM output, the error modes are indicated by a

changing PWM frequency and duty-cycle. For SENT output a dedicated error code will be

transmitted.

The devices are designed for automotive and industrial applications and operate in a

junction temperature range from 40 °C up to 170 °C.

The sensors are available in a four-pin leaded transistor package TO92UP, as well as in

a SOIC8 package.

1.1. Major Applications

Due to the sensor’s versatile programming characteristics and its high accuracy, the

HAL 37xy is the optimal system solution for applications such as:

– Linear movement measurement,

• EGR valve position

• Clutch pedal position

• Cylinder and valve position sensing

– Rotary position measurement, like

• Gear selector

• Throttle valve position, etc.

• Chassis position sensors (ride-height control) with HAL 371x

– Joystick

– Non-contact potentiometer
