Product details
Overview
TLE4929CXVAM38NAHAMA1 from Infineon is a fully programmable, differential Hall-effect crankshaft sensor IC with integrated 220 nF and 1.8 nF capacitors, designed for automotive engine position/speed sensing. It delivers ±0.015° crank jitter (3σ), supports direction detection up to 1800 Hz, and operates across −40 °C to +175 °C junction temperature.
For engineers reviewing the TLE4929CXVAM38NAHAMA1 datasheet, TLE4929CXVAM38NAHAMA1 pinout, TLE4929CXVAM38NAHAMA1 application, or TLE4929CXVAM38NAHAMA1 equivalent, key selection criteria include stop-start phase accuracy (−1.7° to +3.2° crank), adaptive hysteresis configuration, EEPROM-programmable DNC_MIN and HYST settings, and differential stray-field immunity in PG-SSO-3-52 package.
Technical Context
The TLE4929CXVAM38NAHAMA1 implements a dual-Hall differential architecture with separate speed and direction channels, enabling robust operation under magnetic stray fields and thermal drift. Its internal ADCs digitize magnetic field differences with ±120 mT dynamic range on the speed channel and ±60 mT on the direction channel.
It features a four-phase operational sequence (Power-on → Initial → Calibration → Running) with embedded Stop-Start Watchdog and System Watchdog logic. The serial interface supports end-of-line programming of EEPROM parameters including DNC_MIN, HYST, and POLE_WHEEL mode, all validated over 100 write cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.0–16 V continuous - supports direct connection to automotive battery without external regulator |
| Jitter (3σ) | 0.015° crank at ΔB = 20 mTpkpk - enables precise ignition timing control in high-RPM engines |
| Direction Detection Range | 0–1800 Hz increasing / 0–1500 Hz decreasing - covers full engine cranking-to-redline operation |
| Operating Junction Temp | −40 °C to +175 °C - qualified for under-hood placement near cylinder heads and turbochargers |
| Stop-Start Phase Error | −1.7° to +3.2° crank - limits first-pulse timing error after engine restart, critical for start-stop systems |
| EEPROM Endurance | 100 programming cycles - sufficient for factory calibration and final engine parameter tuning |
| Magnetic Differential Field (Stop-Start) | ≥6 mTpkpk - ensures no false pulses during ≤40 K thermal drift after engine shutdown |
Pinout & Package
Package: PG-SSO-3-52 - surface-mount, RoHS-compliant 3-pin leadframe package with integrated 220 nF (CVDD) and 1.8 nF (CQ) capacitors for enhanced EMC performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply input | Accepts 4–16 V; clamped at 42 V for ESD/overvoltage protection; powers internal regulators and Hall elements |
| GND | Ground reference | Common return for supply, output, and internal analog/digital blocks; referenced to CVDD and CQ capacitors |
| Q | Digital open-drain output | Active-low pulse train; requires external 1.2 kΩ pull-up; supports diagnosis via serial protocol edge timing |
Key Features
| Feature | Design Value |
|---|---|
| Differential magnetic sensing | Rejects common-mode stray fields up to ±30 mT difference between outer Hall probes - eliminates need for magnetic shielding |
| Programmable stop-start behavior | Configurable DNC_MIN (0.53–5.56 mTpkpk) and HYST (0.53–1.78 mTpkpk) via EEPROM - adapts to specific engine wheel geometry and thermal profile |
| Direction detection algorithm | Validates rotational direction using phase relationship between speed and direction channel outputs - enables reverse gear detection and misfire monitoring |
| Integrated decoupling capacitance | 220 nF CVDD and 1.8 nF CQ embedded on lead frame - reduces PCB component count and improves EMC immunity without external caps |
| High-speed mode | Supports up to 10 kHz magnetic signal frequency with <19 µs delay - suitable for high-resolution encoder wheels and turbocharger RPM sensing |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar crankshaft sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE4927-2M | Fixed hysteresis, no EEPROM programming; lower max frequency (4 kHz); no direction detection | Limited to basic speed-only applications without stop-start or reverse detection | Select when cost sensitivity outweighs programmability and advanced diagnostics |
| ATS685LSG-T | Two-wire current-output (4–20 mA), no integrated capacitors, wider air-gap capability (up to 3.5 mm) | Better suited for legacy two-wire harnesses and high-vibration environments where voltage-drop immunity is critical | Select for retrofit applications requiring minimal wiring change and higher mechanical tolerance |
Compared with TLE4929CXVAM38NAHAMA1, TLE4927-2M sacrifices programmability and direction detection for lower BOM cost, while ATS685LSG-T trades digital diagnostics and integrated EMC for analog robustness and harness compatibility - making the TLE4929C optimal for new-generation start-stop ECUs requiring precision and configurability.

FAQ
What is the maximum allowable air gap for reliable operation?
The TLE4929CXVAM38NAHAMA1 achieves reliable switching with air gaps up to 2.5 mm when paired with standard ferrous tooth wheels and magnets delivering ≥6 mTpkpk differential field. Its high sensitivity and integrated capacitors maintain signal integrity even with mechanical tolerances typical in cast-aluminum engine blocks.
Does it require an external pull-up resistor?
Yes - a 1.2 kΩ ±10% pull-up resistor is mandatory on the Q pin to ensure proper logic levels and rise/fall times. This resistor sets the output current limit (≤15 mA) and interacts with the integrated 1.8 nF CQ capacitor to meet specified 4–11.4 µs rise time across temperature.
Can it be used for camshaft sensing?
Yes - the device supports camshaft sensing in back-bias configuration with a static field range of 0–550 mT on outer Hall probes. Its differential architecture and programmable offset DAC allow adaptation to pole-wheel or gear-wheel cam targets without hardware changes.
How is EEPROM programming performed in production?
End-of-line programming uses the integrated serial interface (diagnostic mode) with Infineon's TLE4929C Programming Kit. Parameters like DNC_MIN, HYST, and POLE_WHEEL are written during final test using standardized SENT or PWM-based protocols, verified via checksum and read-back confirmation.
