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.

It features a Hall-plate with spinning current offset compensation technique and a precise temperature sensor which is used for temperature compensation of both the Hall sensors sensitivity and offset.

Features

High precision linear Hall-effect sensor

Spinning-current offset compensation

Built-in temperature sensor

Operating junction temperature range: −40 °C… 140 °C

Customer-programmable temperature compensation of Hall-sensitivity (2nd order) and Hall-offset (1st order)

Overvoltage and reverse voltage protection at all pins.

Magnetic characteristics extremely robust against mechanical stress

Digital signal processing

High-precision low-pass filter with constant gain at the pass band and a high attenuation at the stop band. Sample frequency adjustable to 27 Hz and 54 Hz.

12 bit resolution

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

Integrated LIN physical layering

Major Applications

Due to the sensor’s versatile programming characteristics and low drifts, the HAL 2810 is the optimal system solution for applications such as:



Contactless potentiometers

Angular measurements (e.g. for fuel-level sensing)

Linear movement (e.g. Seat track position)

Linear force or torque measurements
