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


Description : LINEAR HALL EFFECT SENSOR

DESCRIPTION
UTC UHS49 LINEAR HALL-EFFECT SENSOR is small, versatile LINEAR HALL-EFFECT device that is operated by the magnetic field from a permanent magnet or an electromagnet. The LINEAR sourcing output voltage is set by the supply voltage and varies in proportion to the strength of the magnetic field. The IC features low noise output, which makes it unnecessary to use external filtering. It also includes thin film resistors to provide increased temperature stability and accuracy. The LINEAR HALL SENSOR can be used for Motor control, Magnetic code reading, Ferrous metal detector, Current sensing and Position sensing .

FEATURES
* Low-Noise Output
* 4.5 V ~ 6 V Operation
* Magnetically Optimized Package
* Miniature construction
* LINEAR output for circuit design flexibility
* Wide ambient temperature range: -40°C ~ +85°C

Description : Micro Power 3 V LINEAR HALL EFFECT SENSORs with Tri-State Output and User-Selectable Sleep Mode

Micro Power 3 V LINEAR HALL EFFECT SENSORs with Tri-State Output and User-Selectable Sleep Mode



Description

The A139x family of LINEAR HALL EFFECT SENSOR integrated circuits (ICs) provide a voltage output that is directly proportional to an applied magnetic field. Before amplification, the sensitivity of typical HALL EFFECT ICs (measured in mV/G) is directly proportional to the current flowing through the HALL EFFECT transducer element inside the ICs. In many applications, it is difficult to achieve sufficient sensitivity levels with a HALL EFFECT SENSOR IC without consuming more than 3 mA of current.



Features and Benefits

▪ High-impedance output during sleep mode

▪ Compatible with 2.5 to 3.5 V power supplies

▪ 10 mW power consumption in the active mode

▪ Miniature MLP/DFN package

▪ Ratiometric output scales with the ratiometric supply reference voltage (VREF pin)

▪ Temperature-stable quiescent output voltage and sensitivity

▪ Wide ambient temperature range: –20°C to 85°C

▪ ESD protection greater than 3 kV

▪ Solid-state reliability

▪ Preset sensitivity and offset at final test

Part Name(s) : OHB900
Optek Technology
Optek Technology
Description : HALLogic HALL EFFECT SENSOR Assembly

Description:
The OHB900 consists of a HALL EFFECT SENSOR similar to the OH180U and a rare earth magnet mounted in a low cost plastic housing. The magnet produces optimum magnetic flux at the HALL EFFECT SENSOR location. The SENSOR has an open collector transistor output which is activated when the slot is open. When the slot is blocked by a ferrous material, reducing the magnetic flux density at the HALL EFFECT SENSOR location, the open collector output transistor switches off. The device provides up to 25 mA of sink current. Output characteristics are constant at switching frequencies from DC to over 200 kHz.

Features:
• Non-contact motion sensing
• Operates over a broad range of supply voltages
• Excellent temperature stability
HALL element, LINEAR amplifier, and Schmitt trigger on a single HALLogic silicon chip
• Performs in high dust and dirt environments over a wide temperature range
• 0.125” (3.18mm) wide gap
