Product details
Overview
TLE4929CXHAM18NHAMA1 from Infineon is an automotive-grade active Hall-effect speed and direction sensor in PG-SSO-3-53 package, designed for crankshaft position sensing with 0–8 kHz magnetic signal frequency support, ±120 mT differential speed channel dynamic range, and integrated 100 nF/50 V supply decoupling capacitor. It enables backward-compatible tooth-wheel detection with programmable switching threshold (K-FACTOR) and Stop-Start algorithm for electric drive calibration.
For engineers reviewing the TLE4929CXHAM18NHAMA1 datasheet, TLE4929CXHAM18NHAMA1 pinout, TLE4929CXHAM18NHAMA1 application, or TLE4929CXHAM18NHAMA1 equivalent, key selection criteria include magnetic jitter performance at low speeds (<1500 Hz direction detection), hybrid calibration robustness across temperature drift (≤60 K), and integrated capacitive decoupling eliminating external CVDD placement.
Technical Context
The TLE4929CXHAM18NHAMA1 implements a differential Hall-sensing architecture with three integrated Hall elements: two outer probes for speed detection and one center probe for direction discrimination. Its Hybrid-Algorithm continuously recalibrates offset during operation using EEPROM-stored parameters, enabling stable performance under thermal transients up to 60 K.
It supports dual-edge timing protocols (forward on edges / backward on PWM), includes four selectable delay time options (10–28 µs), and features system-level watchdogs-Stop-Start, Time, and Hybrid Vehicle Watchdog-to ensure functional safety compliance in ASIL-B contexts. The serial interface allows configuration of K-FACTOR and operational modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.0–16 V continuous - supports direct connection to automotive battery without external regulator |
| Magnetic Signal Frequency | 0–8000 Hz full accuracy - covers idle-to-redline crankshaft speeds in ICE and hybrid powertrains |
| Differential Speed Channel DR | ±120 mT - rejects stray fields while maintaining sensitivity to small tooth-wheel gaps |
| Direction Detection Range | 0–1800 Hz increasing / 0–1500 Hz decreasing - ensures reliable rotation sense at cranking speeds |
| Output Fall Time | 2.0–3.0 µs - enables precise edge timing for ECU-based ignition/fuel injection synchronization |
| Integrated CVDD | 100 nF/50 V - eliminates PCB layout dependency for supply filtering and improves EMC immunity |
| Junction Temp Limit | −40 to +175 °C (2500 h) - qualified for under-hood placement near engine blocks and transmissions |
Pinout & Package
Supplied in PG-SSO-3-53 (Plastic Small Outline, 3-pin, 5.3 mm body width), RoHS-compliant surface-mount package with integrated lead-frame capacitors. Package dimensions conform to Infineon standard SSO-3 outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD | Supply input | Accepts 4–16 V DC; internal clamp diode limits to 42 V transient; powers internal analog/digital blocks |
| GND | Ground reference | Common return path for supply and output; critical for differential Hall bias stability and noise rejection |
| Q | Open-drain output | Active-low digital output; requires external pull-up (1.2 kΩ typical); sinks ≤15 mA at VQ_LOW < 0.5 V |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Switching Threshold (K-FACTOR) | Adjusts hysteresis dynamically via EEPROM to maintain zero-crossing accuracy across magnet aging and air-gap variation |
| Stop-Start Algorithm | Tracks baseline offset during vehicle standstill to eliminate false pulses caused by thermal drift in electric drive systems |
| Differential Sensing Architecture | Rejects common-mode stray fields >30 mT difference between outer Hall probes - essential for noisy engine bay environments |
| Hybrid Calibration | Combines real-time analog averaging with EEPROM-stored correction coefficients to sustain <10% jitter degradation up to 10 kHz |
| System Watchdogs | Three independent watchdogs (Stop-Start, Time, Hybrid Vehicle) detect output lockup or timing violation per ISO 26262 ASIL-B requirements |
Applications
| Crankshaft Position Sensing | Transmission Input Speed Sensing |
|---|---|
|
Use Scenario: Detecting tooth passage on crankshaft wheel for engine control unit (ECU) timing. IC Role / Device Role / Timing Role: Provides synchronized falling-edge pulses aligned to tooth leading edge with <19 µs delay tolerance.

Use Value: Supports adaptive shift scheduling and clutch slip detection using dual-edge protocol and 1500 Hz decreasing-frequency capability. |
| Electric Power Steering (EPS) Motor Rotor Position | Hybrid Starter-Generator Speed Feedback |
|
Use Scenario: Measuring rotor position in brushless EPS motors where compact packaging and thermal resilience are critical. IC Role / Device Role / Timing Role: Acts as high-accuracy speed feedback element interfacing directly with motor controller MCU GPIO. Use Value: Integrated 100 nF CVDD and −40 to +175 °C rating eliminate need for external filtering and enable placement adjacent to motor housing. |

Use Value: Hybrid-Algorithm maintains calibration across rapid thermal cycles (ΔT ≤ 60 K), preventing false zero-speed errors during electric-only propulsion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar active Hall speed and direction sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE4929C-XHA-M38N | 470 nF/25 V integrated CVDD instead of 100 nF/50 V; higher capacitance optimized for 12 V systems with larger voltage ripple | Preferred for 12 V battery architectures with high alternator ripple; less suitable for 5 V regulated subsystems | Select M38N when supply rail exhibits >100 mVpp ripple; M18N preferred for low-noise 5 V domains or space-constrained layouts |
| TLV4929-2K | Single-ended Hall architecture (no direction detection); no integrated capacitors; lower quiescent current (5.5 mA typ.) | Limited to unidirectional speed sensing only; requires external CVDD and lacks Stop-Start algorithm | Choose TLV4929-2K only for cost-sensitive, non-directional applications where thermal drift compensation is handled externally |
Compared with TLE4929CXHAM18NHAMA1, the M38N variant trades voltage headroom for enhanced ripple suppression, while TLV4929-2K sacrifices direction awareness and integrated calibration for reduced BOM count and power draw - neither offers drop-in replacement capability due to pinout and feature set divergence.

FAQ
What is the purpose of the integrated 100 nF capacitor in TLE4929CXHAM18NHAMA1?
The integrated 100 nF/50 V capacitor (CVDD) is mounted directly on the lead frame between VDD and GND pins. It provides localized high-frequency decoupling to suppress supply noise induced by nearby ignition coils or solenoids, eliminating PCB routing inductance and improving EMC performance without requiring external components.
Does TLE4929CXHAM18NHAMA1 support bidirectional rotation detection out of the box?
Yes - it natively supports direction detection using its differential Hall architecture and center probe. Direction is determined by phase relationship between speed and direction channels, validated across 0–1800 Hz (increasing) and 0–1500 Hz (decreasing) ranges, with configurable thresholds via EEPROM programming.
Can TLE4929CXHAM18NHAMA1 operate without an external pull-up resistor?
No - the Q pin is an open-drain output requiring an external pull-up resistor (typically 1.2 kΩ). Without it, the output remains floating and cannot drive a logic-high level; omission causes undefined ECU input states and potential misfire or stall conditions.
How does the Stop-Start Algorithm prevent false pulses during thermal transients?
The Stop-Start Algorithm continuously monitors the differential Hall output baseline during stationary periods. When temperature changes cause offset drift (up to 60 K), it adjusts the switching threshold in real time using stored DAC values, ensuring no spurious edges occur during engine restart or electric-only propulsion transitions.
