Product details

Overview

TLE4929CXVAM18AAHAMA1 from Infineon is a fully programmable, differential Hall-effect crankshaft position sensor with integrated 220 nF and 1.8 nF capacitors, designed for automotive engine management systems. It delivers high-accuracy speed and direction detection (0–1800 Hz), low jitter (≤0.025° Crank at 150°C), and robust stray-field immunity in PG-SSO-3-52 package.

For engineers reviewing the TLE4929CXVAM18AAHAMA1 datasheet, TLE4929CXVAM18AAHAMA1 pinout, TLE4929CXVAM18AAHAMA1 application, or TLE4929CXVAM18AAHAMA1 equivalent, this device supports end-of-line programming for engine-specific calibration, stop-start algorithm execution, and dual-mode operation as crankshaft or differential camshaft sensor under extended temperature (−40°C to +175°C).

Technical Context

The TLE4929CXVAM18AAHAMA1 implements a dual-Hall differential sensing architecture with adaptive hysteresis (0.75–2.5 mTpk-pk) and real-time offset compensation across outer and center Hall elements. Its digital output supports programmable protocols including diagnosis interface and direction detection via phase-difference analysis of two magnetic channels.

It operates across 4.0–16 V supply, features internal ESD protection (±6 kV HBM), and embeds EEPROM for up to 100 programming cycles. The device executes four-phase operation (power-on → initial → calibration → running), includes system and stop-start watchdogs, and supports high-speed mode for >8 kHz signal tracking with <19 µs delay and <5.8 µs fall time.

Key Specifications

Supply Voltage	4.0–16 V continuous - enables direct connection to automotive battery without external regulator
Jitter (3σ)	≤0.025° Crank at ΔB = 9 mTpk-pk, 150°C - ensures precise ignition timing under thermal stress
Direction Detection Range	0–1800 Hz increasing / 0–1500 Hz decreasing - supports fast-cranking and hybrid stop-start transitions
Magnetic Dynamic Range (Speed)	±120 mT ADC range - accommodates large air gaps and varying magnet strengths in production engines
Output Rise/Fall Time	4–11.4 µs rise / 2.0–5.8 µs fall (RPullup = 1.2 kΩ, CQ = 1.8 nF) - ensures clean edge integrity for ECU clock-sampling
Operating Junction Temp	−40°C to +175°C (2500 h @ 175°C) - qualified for under-hood placement near cylinder heads
EEPROM Endurance	100 programming cycles - sufficient for final calibration during engine assembly or service reprogramming

Pinout & Package

Package: PG-SSO-3-52 - surface-mount, RoHS-compliant, three-terminal leadframe package with integrated 220 nF (CVDD) and 1.8 nF (CQ) capacitors embedded on-chip for enhanced EMC performance.

Pin/Terminal	Circuit Role	Design Meaning
VDD	Supply input	Accepts 4–16 V; clamped at 42 V for load-dump protection; powers internal regulators and Hall front-end
GND	Ground reference	Common return for supply, output, and internal bias networks; referenced to CVDD capacitor node
Q	Digital output	Open-drain N-channel output requiring external pull-up (1.2 kΩ typical); sinks ≤15 mA; VQsat ≤500 mV

Key Features

Feature	Design Value
Programmable Output Protocol	Configurable serial interface with diagnosis capability - enables OEM-specific fault reporting and diagnostics integration
Differential Stray-Field Rejection	Robustness against external magnetic interference via dual-Hall topology - eliminates need for shielding in crowded engine bays
Stop-Start Algorithm	Detects zero-speed state and restarts reliably after temperature drift ≤60 K - prevents false pulses during cold starts
Backward-Compatible Switching Point	Centered switching point relative to tooth edge - maintains compatibility with legacy crankwheel designs without hardware change
End-of-Line Programmability	EEPROM configuration post-assembly - allows final calibration to engine-specific parameters (e.g., air gap, magnet grade, wheel geometry)

Applications

Engine Crankshaft Position Sensing

Hybrid Vehicle Stop-Start Control

Use Scenario: Real-time angular position and rotational speed measurement of crankshaft in gasoline/diesel ICEs for ignition and fuel injection timing.

IC Role / Device Role / Timing Role: Primary crankshaft sensor providing synchronized digital pulse train with sub-degree phase accuracy and direction flag.

Use Value: Enables ±0.2° Crank phase error during running and ≤3.2° after stop-start - critical for compliance with Euro 6/China 6 emission control logic.

Use Scenario: Detecting engine standstill and immediate restart during urban driving cycles in 48 V mild-hybrid and start-stop systems.

IC Role / Device Role / Timing Role: Dual-role sensor delivering both speed signal and reliable zero-speed confirmation with temperature-compensated differential field threshold.

Use Value: Guarantees zero false pulses after stop-start events with ≤60 K ambient shift - avoids unintended engine re-ignition or torque interruption.

Differential Camshaft Sensing

Industrial Speed Monitoring

Use Scenario: Measuring camshaft position and valve timing in variable valve timing (VVT) systems using differential pole-wheel configurations.

IC Role / Device Role / Timing Role: Repurposed as differential cam sensor leveraging identical Hall pair architecture and programmable offset compensation.

Use Value: Eliminates need for separate cam sensor BOM item - reduces cost and PCB space while maintaining ±10 mT static range for encoder wheels.

Use Scenario: High-accuracy RPM monitoring in industrial gearmotors, conveyor drives, and turbine control systems requiring low-jitter feedback.

IC Role / Device Role / Timing Role: Robust speed sensor operating over −40°C to +150°C ambient with 8000 Hz full-accuracy bandwidth.

Use Value: Supports predictive maintenance algorithms via stable 0.015° Crank jitter at 20 mTpk-pk - enables early bearing wear detection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar crankshaft position sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLE4929C-XAN-M28	Preprogrammed EEPROM (locking enabled), marking "29AIC0", same PG-SSO-3-52 package	No field reprogramming capability - suitable for high-volume fixed-calibration deployments	Select when calibration parameters are finalized pre-production and no post-assembly tuning is required
TLE4929C-XAF-M28	Unlocked EEPROM (field-programmable), marking "29AIC1", identical electrical specs and package	Supports recalibration during service or engine remap - requires secure programming interface	Select for flexible calibration workflows, R&D validation, or aftermarket engine tuning support

Compared with TLE4929CXVAM18AAHAMA1, the XAN-M28 offers factory-set stability but sacrifices adaptability, while the XAF-M28 matches full programmability at equal performance - all three share identical pinout, timing, and thermal behavior, differing only in EEPROM lock state and marking.

FAQ

What is the maximum allowable air gap for reliable operation?

The TLE4929CXVAM18AAHAMA1 achieves reliable switching with air gaps up to 3.5 mm using standard NdFeB magnets (Br ≈ 1.2 T), enabled by high sensitivity (±120 mT dynamic range) and integrated capacitive filtering. Performance depends on magnet strength and wheel geometry - design validation with actual mechanical stack-up is required per application.

Does it require an external pull-up resistor?

Yes - the open-drain Q output mandates an external pull-up resistor (typically 1.2 kΩ) between VDD and Q. This sets output current limit (≤15 mA), defines rise time, and ensures logic-level compatibility with downstream ECUs. No internal pull-up is provided.

How is direction detection implemented physically?

Direction detection uses phase comparison between two differential Hall channels sampling the same magnetic field at spatially offset positions. The resulting time-shift between zero-crossings determines rotation direction, validated across 0–1800 Hz with dedicated hysteresis and averaging algorithms to suppress noise-induced errors.

Can it operate with 5 V supply only?

Yes - the device operates from 4.0 V to 16 V, making it compatible with both 5 V microcontroller domains and direct 12 V automotive battery connections. At 5 V, output fall time is 2.0–3.0 µs and rise time is 4–11.4 µs with specified RPullup and CQ loading.
