HAL^®2810

Linear Hall-Effect Sensor with LIN Bus

The HAL 2810 is a member of the Micronas

family HAL 28xy of programmable linear

Hall-effect sensors.

Features

Major Applications

High precision linear Hall-effect sensor

Due to the sensor’s versatile programming

characteristics and low drifts, the HAL 2810

is the optimal system solution for applica-

tions such as:

Spinning-current offset compensation

Built-in temperature sensor

It features a Hall-plate with spinning current

offset compensation technique and a pre-

cise temperature sensor which is used for

temperature compensation of both the Hall-

sensors sensitivity and offset.

Operating junction temperature range:

−40 °C…140 °C

Contactless potentiometers

Angular measurements

(e.g. for fuel-level sensing)

Customer-programmable temperature

compensation of Hall-sensitivity (2

order) and Hall-offset (1 order)

The sensor provides a digital signal pro-

cessing. This is of great benefit because

analog offsets, temperature shifts, and

mechanical stress do not degrade digital

signals.

Linear movement

(e.g. Seat track position)

Overvoltage and reverse voltage protec-

tion at all pins.

Linear force or torque measurements

Magnetic characteristics extremely

robust against mechanical stress

The HAL 2810 is designed as a LIN slave

according to the LIN Specification Package

Rev. 2.0. All communications (program-

ming, diagnostics, and measurement sig-

nal transport) is realized by means of LIN

frames.

Digital signal processing

High-precision low-pass filter with con-

stant gain at the pass band and a high

attenuation at the stop band. Sample fre-

quency adjustable to 27 Hz and 54 Hz.

12 bit resolution

Major characteristics like magnetic field

range, sensitivity, offset and the tempera-

ture coefficients of sensitivity and offset can

easily be adjusted to the magnetic circuit by

programming the non-volatile memory.

Non-volatile EEPROM with redundancy

and lock function

LIN slave according to LIN Specification

Package Rev. 2.0

Supported LIN baud rates:

10.4 kbps and 20 kbps

The HAL 2810 is available in the very small

leaded package TO-92UT.

Integrated LIN physical layering
