Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TLE4998P8D linear Hall effect sensor is specially designed to meet the requirements of high-precision Angle and position detection. This sensor provides a digital PWM signal and is suitable for direct decoding of the rectangular signal duty cycle measurement unit (typically the timer/capture unit in a microcontroller).

Main characteristics

The features of TLE4998P8D include:

Integrate two independent programmable linear Hall sensor ics with the PWM open-drain output signal.

20-bit digital signal processing

Digital temperature and stress compensation

12-bit overall resolution

The operating temperature range of the vehicle is -40°C to 125°C

The output signal drifts extremely little throughout the entire temperature range and throughout its service life

Programmable parameters are stored in EEPROM and have unit error correction function:

PWM output frequency

Magnetic range, sensitivity (gain), compensation and output slope polarity

Bandwidth

Clamping level

The customized temperature compensation coefficient is applicable to all common magnets

Reprogrammable before memory locking

Power supply voltage: 4.5- 5.5V (Extended range: 4.1- 16V)

Configurable magnetic range: ±50 mT, ±100 mT, or ±200 mT

All pins have reverse polarity and overvoltage protection functions

Output short-circuit protection

On-board diagnosis (overvoltage, EEPROM error)

Digital readings of the magnetic field and internal temperature in the calibration mode

Programming and Operation of multi-sensors for General Power Supply

Two-point calibration of the magnetic transfer function without iterative steps

Application field

The TLE4998P8D sensor is suitable for a variety of high-precision requirements applications, including:

Potentiometer replacement is stable: no mechanical wear, resistant to moisture, temperature, pollution and vibration.

Linear and angular position sensing in automotive and industrial applications has the highest precision requirements.

Suitable for safety applications, such as pedal position, throttle position and steering torque sensing.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
