Product details

Overview

TLE5045ICIJGR050HALA1 from Infineon is a high-end GMR-based wheel speed sensor compliant with ASIL B(D) per ISO 26262, designed for automotive chassis control systems. It delivers ±0.02% period jitter, operates from -40°C to +190°C junction temperature, and uses a two-wire 7 mA / 14 mA current interface for speed-only output-enabling use in indirect tire pressure monitoring (iTPMS) and ABS/ESC modules.

For engineers reviewing the TLE5045ICIJGR050HALA1 datasheet, TLE5045ICIJGR050HALA1 pinout, TLE5045ICIJGR050HALA1 application, or TLE5045ICIJGR050HALA1 equivalent, key selection criteria include its differential GMR sensing architecture, 2 mT immunity to external magnetic disturbance, R_m ≤ 50 Ω load resistor compatibility, and integrated micro-break feature for supply-line disturbance immunity.

Technical Context

The TLE5045ICIJGR050HALA1 implements a differential giant magneto-resistive (GMR) sensing element sensitive to x-direction magnetic fields, with adaptive hysteresis and zero-crossing detection logic for precise rotational speed measurement. Its signal path includes dynamic offset compensation and calibrated duty cycle control (40–60%) to maintain timing accuracy across air gap and y-displacement variations.

It integrates undervoltage detection and fuse-bit discrepancy monitoring as embedded safety mechanisms, reporting faults via a dedicated 1–3.8 mA error current level. The device requires no external capacitor and achieves EMC robustness per ISO 7637-2/3 and CISPR 25 through an on-die advanced EMC concept including the Micro Break feature.

Key Specifications

Parameter	Value and Actual Design Meaning
ASIL Level	Compliant with ASIL B(D) per ISO 26262; supports integration into ASIL D systems with system-level safety measures.
Period Jitter	±0.02% (1σ); enables sub-millisecond time resolution for iTPMS and high-accuracy wheel speed estimation.
Operating Temp	-40°C to +190°C junction temperature; qualified per AEC-Q100 Grade 0 for under-hood placement.
Output Interface	Two-wire current loop: 7 mA (low), 14 mA (high), 1–3.8 mA (error); eliminates need for voltage-level signaling or external pull-ups.
Magnetic Immunity	Immune to homogeneous external fields up to ±2 mT in X/Y/Z axes; prevents false triggering near motors or solenoids.
Air Gap Performance	High GMR sensitivity enables >1.5 mm usable air gap with stable switching; reduces mechanical tolerance constraints in module assembly.
ESD Robustness	±12 kV HBM (AEC-Q100 Rev H); eliminates need for external ESD protection diodes in PCB layout.

Pinout & Package

Package: PG-SSO-2-1 (5 mm × 3 mm, 2-pin surface-mount small-outline package with exposed thermal pad).

Pin/Terminal	Circuit Role	Design Meaning
1: VDD	Supply input	Accepts 4.25–20 V (R050 variant); includes undervoltage detection with 0.65–0.75 V hysteresis and reset at 3.5 V.
2: GND	Reference ground	Common return for supply and current-output loop; thermally coupled to die for junction temperature stability.

Key Features

Feature	Design Value
Differential GMR Sensing	Rejects common-mode magnetic disturbances while detecting encoder tooth transitions with <110 µT minimum differential amplitude.
Micro Break Function	Internally suppresses transients on VDD line without external RC snubbers-maintains valid output during load-dump or jump-start events.
No External Capacitor Required	Reduces BOM count and PCB area; improves mechanical robustness against vibration-induced solder fatigue in automotive modules.
Calibrated Duty Cycle	40–60% output pulse width stability over temperature and air gap-simplifies downstream edge-counting and frequency-to-voltage conversion.

Applications

ABS / ESC Systems

iTPMS Integration

Use Scenario: Real-time wheel rotation monitoring during braking and cornering maneuvers.

IC Role / Device Role / Timing Role: Primary speed signal source feeding vehicle dynamics controller with low-jitter, fail-safe pulses.

Use Value: ±0.02% jitter ensures <10 µs timing uncertainty per revolution-critical for accurate slip ratio calculation and brake pressure modulation.

Use Scenario: Detecting subtle wheel speed deviations indicating under-inflation.

IC Role / Device Role / Timing Role: High-stability speed reference enabling Δ-speed comparison between axles without calibration drift.

Use Value: Stable 7–14 mA current output and wide -40°C to +190°C operation ensure consistent performance across seasonal and under-hood thermal cycles.

Electric Power Steering (EPS)

Transmission Speed Sensing

Use Scenario: Measuring rack position speed for assist torque calculation and fault detection.

IC Role / Device Role / Timing Role: Robust speed feedback element immune to motor EMI and gear backlash-induced signal noise.

Use Value: ±2 mT magnetic immunity prevents false pulses from EPS motor stray fields; eliminates need for magnetic shielding.

Use Scenario: Input/output shaft speed monitoring in dual-clutch and automatic transmissions.

IC Role / Device Role / Timing Role: High-temperature tolerant speed sensor mounted near gearbox housing with minimal thermal derating.

Use Value: 190°C max junction temperature rating allows direct mounting on transmission casing-reducing harness length and signal degradation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar wheel speed sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE5046ICIJGR050HALA1	Includes direction detection (quadrature output); higher pin count (3-pin); 0.03% jitter.	Required for traction control or parking assist where rotational direction matters.	Select only if bidirectional sensing is mandatory; otherwise TLE5045 offers lower cost and smaller footprint.
ATS6849LSGT-T	Hall-effect based; 0.05% jitter; -40°C to +150°C rating; requires external capacitor.	Limited to mid-temperature under-hood locations; less suitable for iTPMS due to higher jitter.	Consider for cost-sensitive non-safety-critical applications where 190°C operation is not required.

Compared with TLE5045ICIJGR050HALA1, the TLE5046 variant adds directionality at the cost of package size and complexity, while the ATS6849 offers Hall-based simplicity but sacrifices ASIL compliance, temperature range, and jitter performance critical for iTPMS and ESC.

FAQ

What is the maximum allowable air gap for reliable operation of TLE5045ICIJGR050HALA1?

The sensor maintains reliable switching up to 1.5 mm air gap when used with standard ferrous encoder wheels and nominal magnet strength. This is enabled by its high GMR sensitivity (70–110 µT dBlimit_x at 25°C) and differential topology, which rejects y-axis displacement effects that degrade single-element sensors.

Does TLE5045ICIJGR050HALA1 require an external decoupling capacitor?

No. The device integrates all necessary regulation and filtering circuitry and is explicitly qualified to operate without any external capacitor-reducing PCB area, BOM count, and failure modes related to capacitor aging or thermal cycling in automotive environments.

How does the Micro Break feature protect against supply-line disturbances?

The Micro Break feature detects fast-rising transients on VDD (e.g., load dump, jump start) and temporarily suspends output switching while maintaining valid current levels. It recovers autonomously within microseconds without requiring system reset or external intervention-preserving signal integrity during electrical stress events.

Can TLE5045ICIJGR050HALA1 be used in ASIL D systems?

Yes-while certified to ASIL B(D), the device is architected for use in ASIL D systems when combined with appropriate system-level safety mechanisms (e.g., redundancy, plausibility checks, watchdog supervision). Its safety manual and FMEDA report support integration into full ISO 26262-compliant architectures.
