Product details
Overview
TLE4998C8DXUMA2 from Infineon Technologies is a dual-die programmable linear Hall sensor IC with two independent SPC (Short PWM Code) output channels, 20-bit digital signal processing, ±100 mT magnetic range, and AEC-Q100 qualification for automotive position sensing. It delivers 16-bit resolution, digital temperature/stress compensation, and operates from -40°C to +125°C with 4.5–5.5 V supply.
For engineers reviewing the TLE4998C8DXUMA2 datasheet, TLE4998C8DXUMA2 pinout, TLE4998C8DXUMA2 application, or TLE4998C8DXUMA2 equivalent, this device supports synchronous SENT-based transmission, dynamic range switching, and ID-selectable multi-sensor bus operation on a single output line - critical for pedal, throttle, and steering torque sensing in ASIL-B systems.
Technical Context
The TLE4998C8DXUMA2 integrates two physically separate Hall sensor dies in one PG-TDSO-8-2 package, each with independent EEPROM-programmable parameters including gain (sensitivity), offset, polarity, bandwidth, clamping levels, and magnet-specific temperature compensation coefficients. Its BiCMOS process enables reverse-polarity and overvoltage protection on all pins.
It implements the SAE J2716-compliant SPC protocol with three operational modes: synchronous transmission, synchronous + range selection, and synchronous + ID selection (supporting up to four sensors on one output line). The open-drain output stage requires an external pull-up resistor and supports mixed-voltage receivers (e.g., 3.3 V MCU interfacing with 5 V sensor supply).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Protocol | SPC (Short PWM Code) based on SENT SAE J2716 - enables ECU-initiated transmissions and diagnostics-ready nibble framing. |
| Magnetic Range | Configurable ±50 mT / ±100 mT / ±200 mT - selectable per die to match magnet strength and air gap in mechanical assembly. |
| Resolution | 16-bit overall (65535 steps) with 20-bit internal DSP - ensures sub-millitesla field discrimination under thermal drift. |
| Temperature Range | -40°C to +125°C - qualified per AEC-Q100 Grade 0, enabling direct placement near engine compartments or brake actuators. |
| Supply Voltage | 4.5–5.5 V nominal (4.1–16 V extended) - accommodates battery transients without external LDO, reducing BOM count. |
| Protection Features | Reverse-polarity, output short-circuit, overvoltage (±18.35 V), and on-board diagnostics (EEPROM error, overvoltage detection) - eliminates need for discrete protection circuitry. |
| Calibration | Two-point magnetic transfer function calibration without iteration - reduces production test time and fixture complexity. |
Pinout & Package
Package: PG-TDSO-8-2 (8-pin thermally enhanced SOIC, dual-die layout with isolated top/bottom die connections).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 (TST) | Test pin (top die / bottom die) | Internally connected to test logic; recommended to tie to GND for stable operation and noise immunity. |
| 2, 7 (VDD) | Supply voltage input (top die / bottom die) | Independent power rails per die enable fault-isolated operation; supports 4.1–16 V with built-in overvoltage clamp. |
| 3, 6 (GND) | Ground reference (top die / bottom die) | Dedicated ground paths minimize crosstalk between dies and improve common-mode rejection in noisy automotive environments. |
| 4 (OUT) | SPC output (top die) | Open-drain driver - requires external pull-up; compatible with 3.3 V or 5 V receivers depending on pull-up source. |
| 5 (OUT) | SPC output (bottom die) | Second independent SPC channel - enables dual-axis or redundancy sensing without additional interface ICs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent Hall dies | Two fully configurable sensors in one PG-TDSO-8-2 package - reduces PCB area and interconnect complexity vs. discrete dual-sensor solutions. |
| EEPROM-programmable parameters | All key magnetic and timing settings stored in EEPROM with single-bit error correction - enables field reconfiguration and end-of-line calibration. |
| Digital temperature compensation | Second-order polynomial compensation using on-chip temperature sensor - eliminates external thermistor and lookup tables. |
| ID-selectable bus mode | Up to 4 TLE4998x devices share one output line and supply rail while responding to unique ECU commands - cuts wiring harness weight and connector pins. |
| On-board diagnostics | Detects EEPROM errors, overvoltage events, and supply faults - provides diagnostic status nibbles in every SPC frame for ISO 26262-compliant monitoring. |
Applications
| Automotive Pedal Position Sensing | Electric Power Steering (EPS) Torque Sensing |
|---|---|
|
Use Scenario: Measuring accelerator/brake pedal angle via magnet displacement on rotating lever. IC Role / Device Role / Timing Role: Dual-die configuration provides redundant analog-path sensing with independent SPC outputs for cross-checking. Use Value: Eliminates potentiometer wear and contamination failure; meets ASIL-B requirements via diagnostic-enabled dual-channel architecture. |
Use Scenario: Detecting torsion bar twist in EPS column using two orthogonal magnets. IC Role / Device Role / Timing Role: One die measures primary torque field; second die monitors auxiliary field or temperature-compensated reference. Use Value: Enables real-time stress compensation and fault detection without external ADC or processor overhead. |
| Throttle Valve Position Monitoring | Industrial Linear Actuator Feedback |
|
Use Scenario: Closed-loop control of engine throttle plate angle in gasoline direct injection systems. IC Role / Device Role / Timing Role: High-resolution (16-bit) linear output with <1% full-scale drift over lifetime - replaces legacy potentiometers. Use Value: Maintains accuracy across -40°C to 125°C ambient without recalibration; supports fail-safe limp-home mode via diagnostics. |
Use Scenario: Position feedback in hydraulic or electric linear actuators for factory automation valves. IC Role / Device Role / Timing Role: Programmable ±200 mT range adapts to large air gaps; SPC output interfaces directly with PLC I/O modules. Use Value: Reduces system cost by eliminating signal conditioning circuitry and enabling direct microcontroller integration. |
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 | Tri-axis I²C/TWI output, 18-bit resolution, no SPC/Sent support; requires external MCU for protocol handling. | Lacks native SENT interface and dual-die integration - needs two ICs and firmware to replicate TLE4998C8DXUMA2's bus mode. | Select when tri-axis field measurement and I²C flexibility outweigh automotive protocol compliance and integration density. |
| Allegro A1324LLHLT-T | Analog ratiometric output (0.5–4.5 V), fixed ±100 mT range, no EEPROM programming or diagnostics. | No digital protocol, no temperature compensation coefficients, no fault reporting - unsuitable for ASIL-B safety goals. | Select only for non-safety-critical industrial analog feedback where cost is primary and diagnostics are handled externally. |
Compared with MLX90393 and A1324LLHLT-T, the TLE4998C8DXUMA2 uniquely combines dual-die SENT output, EEPROM-based field calibration, and integrated diagnostics - making it the only option qualified for ASIL-B pedal/throttle sensing without added interface or safety software layers.

FAQ
What is the difference between TLE4998C8DXUMA2 and TLE4998C8D?
TLE4998C8DXUMA2 is the specific orderable part number for the dual-die variant in PG-TDSO-8-2 package, marked "C8D", and shipped in tape-and-reel per AEC-Q100 release standards. It is functionally identical to TLE4998C8D but denotes Infineon's standardized packaging and traceability format for automotive production use.
Can both output channels operate simultaneously on the same SENT line?
No - the ID selection mode allows only one die to transmit per command cycle. The ECU sends a unique ID to select either top-die (Pin 4) or bottom-die (Pin 5) output; simultaneous transmission would cause bus contention and violates SAE J2716 timing constraints.
Is external EEPROM required for configuration storage?
No - all programmable parameters (gain, offset, range, temperature coefficients, etc.) are stored in on-chip EEPROM with single-bit error correction. No external memory is needed, and reprogramming is supported until memory lock is enabled via dedicated command sequence.
Does the device support functional safety certification documentation?
Yes - Infineon provides a PRO-SIL™ Safety Manual and Safety Analysis Summary Report for TLE4998C8DXUMA2, covering FMEDA, diagnostic coverage analysis, and hardware metrics (SPFM, LFM, PMHF) aligned with ISO 26262 ASIL B requirements.
