Product details

Overview

TLE4998P3XALA1 from Infineon Technologies is a programmable linear Hall sensor IC with PWM open-drain output, 20-bit digital signal processing, and EEPROM-stored calibration parameters. It delivers 12-bit resolution, operates from −40 °C to 150 °C, supports magnetic field ranges up to ±200 mT, and is designed for automotive pedal position and throttle sensing.

For engineers reviewing the TLE4998P3XALA1 datasheet, TLE4998P3XALA1 pinout, TLE4998P3XALA1 application, or TLE4998P3XALA1 equivalent, key selection criteria include programmable gain/offset, digital temperature compensation, PWM frequency setup, EEPROM lock capability, and robust EMC/ESD immunity in harsh automotive environments.

Technical Context

The TLE4998P3XALA1 integrates a Hall plate, analog front-end, 20-bit DSP core, and EEPROM-based configuration memory. Its transfer function is digitally calibrated across temperature using on-chip temperature sensing and customer-programmable coefficients, enabling <±0.5% full-scale error over −40 °C to 150 °C.

It implements a PWM output stage with programmable frequency (1 kHz–20 kHz), clamping levels, and bandwidth control. The open-drain output requires an external pull-up resistor and supports mixed-voltage interfacing (e.g., 5 V sensor with 3.3 V MCU capture input).

Key Specifications

Magnetic Range	±200 mT max - supports wide-field applications including high-current sensing and large-angle rotary position detection
Operating Temp	−40 °C to +150 °C - qualified for under-hood automotive use without derating or external thermal management
Supply Voltage	4.5 V to 5.5 V (4.1–16 V extended) - tolerates battery transients and brown-out conditions in 12 V vehicle systems
DSP Core	20-bit digital signal processor - performs real-time temperature compensation, offset/gain correction, and filtering without host MCU intervention
EEPROM Memory	Configurable parameters with single-bit error correction - stores gain, offset, PWM frequency, clamping, and custom temp-coeffs; reprogrammable until locked

Pinout & Package

Package: PG-SSO-3-10 (Small Outline Sensor, 3-pin, exposed pad). Compact surface-mount package optimized for magnetic field coupling through branded side; Hall element located 0.38 mm below top surface.

Pin/Terminal	Circuit Role	Design Meaning

Equivalent & Alternatives

The following parts are listed as comparable options for similar programmable linear Hall sensor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Melexis MLX90393	I²C/SPI digital output (16-bit), no integrated EEPROM programming interface; requires external MCU for calibration storage	Lacks native PWM output - needs software-based duty-cycle generation or external timer; higher system-level integration effort	Preferred when multi-axis sensing or SPI-configurable filters are needed; not drop-in for PWM-decoding systems
Allegro A1324	Analog ratiometric output (5 V), fixed gain/offset, no programmability or temperature compensation beyond internal trimming	No EEPROM, no digital calibration - limited to ambient-temperature-stable applications; no diagnostic capability	Suitable for cost-sensitive, non-automotive applications where ±2% accuracy and no diagnostics are acceptable

Compared with MLX90393 and A1324, the TLE4998P3XALA1 uniquely combines factory- and field-programmable PWM output, on-chip 20-bit DSP, EEPROM-resident calibration, and automotive-grade diagnostics - reducing system BOM count and enabling end-of-line calibration without host MCU involvement.

FAQ

What programming interface does TLE4998P3XALA1 use?

The device uses a proprietary single-wire pulse-width modulation (PWM) interface shared between VDD and OUT pins. Programming is performed by applying specific voltage pulse trains to VDD while monitoring response patterns on OUT. No dedicated programming pins or external hardware programmers are required - calibration can be done in-system using standard GPIOs and timers.

Does TLE4998P3XALA1 require an external pull-up resistor on the OUT pin?

Yes - the OUT pin is an open-drain driver and must be pulled up externally. The recommended pull-up resistor value is 4.7 kΩ to 5 V, though values from 2.2 kΩ to 10 kΩ are supported depending on rise time and bus capacitance. Pull-up to 3.3 V is allowed for interfacing with lower-voltage MCUs, provided the receiver recognizes 3.3 V logic high.

How is temperature compensation implemented?

Temperature compensation uses an on-chip temperature sensor feeding a 20-bit DSP that applies user-programmed polynomial coefficients stored in EEPROM. These coefficients correct gain, offset, and clamping thresholds across temperature - enabling <±0.5% full-scale error from −40 °C to +150 °C without external lookup tables or MCU intervention.

Can TLE4998P3XALA1 be used without programming?

Yes - it ships with factory-default calibration parameters enabling immediate operation. Default settings include ±100 mT range, 10 kHz PWM frequency, and basic temperature compensation. Full performance (e.g., extended range, custom coefficients, diagnostics enablement) requires programming via the PWM interface, but basic functionality is available out-of-box.
