HAL 2830

Linear Hall-Effect Sensor with SENT Output

The HAL 2830 is a new member of the

Micronas varioHAL (HAL 28xy) family of

programmable linear Hall-effect sensors.

The HAL 2830 is available in the very small

leaded package TO-92UT.

Sample accurate transmission

Telegram length less than 360 µs at 2 µs

tick time

Features

12-bit resolution

It features

(SingleEdgeNibbleTransmission)

digital SENT interface

that

High-precision linear Hall-effect sensor

Spinning-current offset compensation

Built-in temperature sensor

Non-volatile EEPROM with redundancy

and lock function

enables a fast and robust data transfer in

harsh automotive environments.

Open-drain output with slew rate control

Transmission of temperature information

Individual serial number for each sensor

12-bit customer serial number

The implementation of the interface com-

plies with the SAE J2716 SENT standard.

Each message consists of a sequence of

pulses. In one protocol, the sensor trans-

mits the magnetic field information, a status

information of the sensor, and for safety

reasons a CRC checksum.

On-board diagnostics (overtemperature,

overcurrent, etc.)

Customer-programmable temperature

compensation of output sensitivity (2

order) and output offset (1 order)

Major Applications

Operating junction temperature range:

Due to the sensor’s versatile programming

characteristics and low drifts, the HAL 2830

is the optimal system solution for applica-

tions such as:

−40 °C…170 °C.

The HAL 2830 features a Hall-plate with

spinning current offset compensation tech-

nique and a precise temperature sensor

which is used for temperature compensa-

tion of both the Hall-sensors sensitivity and

offset.

Magnetic characteristics extremely

robust against mechanical stress

Digital signal processing

Contactless potentiometers

Sampling rates up to 2 kHz with internal

low-pass filter

Angular measurements

(e.g. valve, throttle, pedal position)

SENT output according to SAE J2716

standard

The sensor provides digital signal process-

ing. 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)

Message tick time customer-program-

mable between 2 µs and 17 µs

Linear force or torque measurements

Current sensing

(e.g. battery management)

Low time customer-programmable

between 3 and 7 clock ticks

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.
